[Q] Audio stutter on 4.3? - Xperia Z Q&A, Help & Troubleshooting

Is anyone else suffering from audio stutter since the update to 4.3 and if so has anyone found a solution? I've read about lots of issues with other devices and music stutter on 4.3 but can't find anything on the Xperia Z.
I'm running the Generic UK rooted update from the Android Dev section, and I have narrowed the stutter down to when the device is sleeping.
At first I had my headphones (MDR-1RBT) on bluetooth and assumed it was that, but after connecting them with the wire the issue continued. Next I switched to Walkman player instead of the Google Music one (all music on both apps is local, on the SD card, not streamed).
The issue still continued, however, every time I wake the device the stuttering stops. I ran CPU spy to see what is going on and noticed my device has never entered deep sleep since the update (is anyone else seeing this also?)
One suggestion was that Wifi optimisation could be the issue, I turned that off, but it didn't help, and even turning wifi off doesn't seem to help, but wifi on seems to make it worse I'd say.
It's driving me insane and I use my phone/headphones to listen to music several hours a day and can't deal with the stutter, I'll have to go back to 4.2.2 unless I find a solution.

Yep. Same problem here.

Same problem as well, except it does not stop when I wake the device - the stutter still continues no matter what. I'm using the default Walkman app as well as have tried other music apps, but same problem throughout

no issues with poweramp. try apollo or some other player (not walkman or play music) and see if that helps.

No stutter here with walkman app.
But if I run the Walkman app, the accu usage shows that Mediaserver sucks my Battery,

Same here and for @AngelBob
It's annoying and I've not been able to find a solution to it yet...

I went back to 4.2.2, so i have one question: can someone test if stuttering are not present using PowerAmp?
Thanks all

I believe it's kernel related. We had this exact issue in the past and Sony fixed with am update.

CM builds are also suffering audio 'stutters' so I think it's something we're going to have to live with until Sony push a new kernel/libs

You're right, after investigation, I can say with some certainty that the cause is the new bluetooth stack Google switched to in 4.3. I tried modifying some of the bluetooth configs but it made no difference. It'll need a fix to those libs and perhaps a kernel update as you say.
I don't know if it's been fixed in 4.4 yet, since I no longer own any nexus devices, but I wouldn't count on us getting the fix any time soon unless Sony decide to resolve it themselves.

You're right, I tested wired and it's the same problem.
In this case, I'm going to put the issue down to kernel and power save/sleep mode. I switched straight back to 4.2.2. I really like the new UI, but I can wait, hopefully 4.4 fixes it. I wouldn't count on a maintenance release from Sony before 4.4

I had this problem on 4.2.2 ROMs when I had Wi-Fi on. I think it was probably due to media server scanning for other devices over Wi-Fi network. It was going crazy when I was at uni as there were so many devices around me. Had to keep my wi-fi disabled just to listen to music.
You guys getting the same issue?

Unfortunately not, even worth wifi disabled it still happens, makes no difference.
It seems to be kernel related, perhaps something to do with cpu states or such because it only happens for me in sleep mode, it also happens when apps install so could be I/O related.

I'm starting to think sony rushed the Z 4.3 update, the T leak does not suffer this bug and it also has transparent nav bar by default!

Can we use bluetooth/a2dp libraries from other devices or versions of Android?
For example can we put Xperia Z 4.2.2 bluetooth files into the Xperia Z 4.3 firmware?
Thanks

On 4.3 Drummerjeds stock pre-rooted and deodexed rom with PXA23 I don't get any stutter when streaming. Is it only a problem with music stored on the device? (Doesn't appear to be an issue either with music from Google Play music stored on my external card). Just wonder if it could be related to my having the kernel tweaks on Power Guard Pro running in learning mode, if it's related to a problem in sleep mode?

Just want to inform you guys that I have no stutter whatsoever with walkman but I'm on the official C6602 4.3 ROM, but the screen sometimes flickers in chrome, the most annoying bug so far

Though I am leaning to the kernel going to sleep causing the issue,

[Q] Songs jumping in walkman player

Has anyone else had issues with tracks jumping or freezing briefly in the walkman player? I've only had it happen a few times, but it never normally happens with the files themselves. Any ideas?
Ill reply this happened previously on one of the last java Sony Ericsson phones think it was the c905 - cant remember. But I fixed it somehow.
Anyways,
Are the songs on phone or memory card?
What bit rate are the songs? What format?

Sound issues
Hello!
I have the same problem with freezing music not only in walkman app, but also in player pro. It happens more often when device is using multitask (for example, browsing and music at the same time), but sometimes there are pauses even if screen is off.
All the media is [email protected] stored on microsd.
And i have never noticed this problem in media apps that use their own media decoder. Sound in videos played by mxplayer is ok, and music has no longer these freezes as i started to use playerpro with DSP pack.
As far as i can see, the problem is caused by software, not hardware. I hope sony will fix it by firmware updates.

any other ideas? this is seriously bugging me - listening to music is probably one of the main things I use my phone for outside of calls/texts
Um have you cleared the cache for the walkman app?
Or like windows pcs.
Clear the phone - factory reset it - start from scratch do a clean wipe.
Try another music player.
Or try a different bit rate mp3

Have done all but cleared the cache and bit rate so will try that today. Also getting my sd card today so will see if it makes any difference once they're on that instead, as is it possible it could be to do with the read speed of the internal memory?
As i have already said, it looks to be walkman app problem.
I have noticed no such issues since i started to use another player app.

See, I'm having the problem regardless of what music app I use, which is a bit weird. Although last night, I wiped all my music again and transferred just a few of the songs, so will continue to see how that goes.
Ok so have tried everything now - different bit rate, clearing the cache, factory reset, phone repair, using different music players, trying it on both internal memory and SD card and it's STILL skipping.
Could this therefore just be a hardware fault?
That's really weird.
You know, i had same problem, some people were reporting about this problem both here and on local russian forums, but the feedback about the issue was not that massive as it would be in case of hardware fault. And at the moment everything works fine on my device.
If you dont mind, i'll contact you in a moment via private message, hope i can provide some help.

I mean if it was a hardware fault just specific to my phone. It's annoying if it is as I haven't experienced all the other issues people have had like dead pixels, LED light problems, stamina mode not working, etc. so would be reluctant to swap my phone and potentially end up with any of those issues.
Had this problem' solved by using player pro and having audio buffer set to very high and priority set to high sorted it for me.

Using player pro with DSP enabled, so will try editing the audio buffer and priority settings as well.
Well, everything is possible.
But i can't see the way for hardware to cause this problem with music, but not to affect any other use-cases of the device. As you said, you experienced no other troubles like random rebooting or graphic disfiguration, which would point to defects of cpu or memory or somewhat.
My guess is that system lets the device to fall into "deep sleep", that's why music decoder stops its work for a moment and causes the freeze. Just a software bug. But i can mistake, though.
Yes, i forgot to notice this: the priority of decoder in dsp settings of playerpro is also set to max.

Ok so I downloaded playerpro from the link you sent me after uninstalling the player pro and DSP pack I already had on my phone and weirdly, it seems to have improved. There's still the occasional jump/pause but nowhere near as bad as it was. Will keep testing and update. If it continues to be buggy though, I still might pop into CPW tomorrow and see whether I should get it swapped.
Update: It seems you could be onto something regarding it going to sleep - I don't know how it would go to sleep so quickly, but in look and feel, when I selected to keep the screen on, and it didn't get locked, I experienced no jumping in the tracks.
Looking at this http://androidforums.com/captivate-...-playback-stock-player-samsung-captivate.html
I wonder if it could be anything to do with CPU throttling? It is definitely the case that it only skips when the screen is off, so I'm assuming I have no way of fixing this.
Anyone able to get Lastfm scrobbling to work with Walkman?
Tried the Xperia App but it only works with the official Lastfm app and it's a piece of crap.

I have sent a request to sony's support via e-mail asking for their response about this music problem. I hope the answer will come today, so i'll post sony representatives' comment on the issue.
Still believe it is software to cause bugs. Playerpro decoder, set to maximum process priority, doesn't let system to sleep, which increases power consumption, but fixes freezes and pauses. The original sound decoder has lesser priority, maybe there are some bugs in power management, so the issue we decribe happens.
The problem is, there can be no firmware updates for XZ until the end of March or beginning of April, when android 4.2 will become available for our device.

[Q] Stuttering audio?

Hey guys, I searched and didn't see anything on this -- even Google did not turn up any results. I saw on the HTC One X sometimes there would be audio stutter/skips with the Beats EQ on. Sometimes when I'm playing music the audio will just glitch and stutter for no apparent reason. It is random. Has anyone else experienced this? It happened with the stock ROM as well as with ARHD7.

I am having this problem with the HTC One, streaming via bluetooth. I have raised the problem with HTC tech and waiting for a response.
I'm finding it hard to believe no one else has this problem. If it's a hardware issue I fully expect HTC to replace my unit. I will even take a recording of the stutter if necessary.
My audio will make weird noise in certain tracks and bass tones out of no where with beats on or off

I had this with my HTC One and it has been reported that it is a wifi issue. Turn it of (wifi) and it should work OK, mine does. It is a pain to keep switching wifi of and on so I found an app called A2DP volume in the play store that does it automatically.

Bumping to see if anyone else has this...
I am having this issue only when stream over BT.

Faulty sdcard possibly or your files are corrupt. Have you done an MP3 check on them?

I'm also experiencing this. Except mine skips/stutters even with beats off.
Running ARHD8.0 stock kernel w/purexaudio. I'm not sure which version of purexaudio the ARHD installed, but I went ahead and installed the most current version (v4.0) to see if it helps. So far no skipping, but I haven't tested that long yet..
There is a known issue that if you are using Adblock or a similar piece of software which modifies the hosts file that Pandora will stutter. Are you using an actual file, or are you using a buffered service that could be having an issue because of this?

It happens in the regular music player too; however I reinstalled ARHD8.1 and am not selecting adaway hosts files. I'll report back on the issue.. Thanks for the tip!
I am not using AdAway, and it happens in Play Music over the headphone jack. Haven't tested it with Bluetooth. I plan on installing TrickDroid sometime soon; I will definitely update this thread when I do and see if it still happens. Curiously, it's been happening less lately. Only once or twice a day.

So I reflashed ARHD8.1 without adblock and Pandora is no longer horribly stuttering. However it still has occasional stutters in both Pandora and Google Music. Still not sure what's causing it.

I reflashed without PureXAudio and the occasional skips/stutters still happens. Maybe once every couple minutes, really annoying considering this happened on my Note 2 also, which is why I bought the HTC One. I initially thought it might be a rogue app, but I don't have anything that could be causing it besides maybe groove IP disconnecting/reconnecting, or tasker. However I disabled both apps and the stutters still happen..

In terms of Bluetooth, the largest thing that could change in the near future would be if we get an official 4.2+ or the rumored 4.3 release, as the BT stack is recoded in that code base. This has the potential to change the game, but really considering your issue still seems to be isolated to your devices and not everyone's though, I've gotta think we're overlooking something. The further clue that you are saying this happened on your Note 2 as well also makes me wonder what else is happening.
Is this stuttering possibly during PBAP, MAP or some other profile saturating the connection with its own traffic? Is this on all BT devices that you've tested against or are we dealing with a dodgy car kit/speaker instead of a phone difficulty?

I dont use blue tooth, this is strictly wired 3.5mm connections. I don't have any uncommon apps besides tasker/secure settings/busybox/grooveip/xposed installer that were on both my note 2 and htc one. The only apps that have SU access are secure settings, xposed installer, seeder, solid explorer, betterbattery stats, and tasker.
I was almost sure that the stutter/skips were caused by purexaudio, but I guess not since I removed it.
I had this as well, does it sound like the stuff in this thread?:

It sounds similar, sometimes the audio would cut out entirely for a third of a second, but it was not happening nearly as frequent as yours. Mine only happened once every couple minutes. Also I have since flashed bulletproof 1.9 kernel with purexaudio 4.0 and the problem seems to have gone away. However, more testing needs to be done..
I'm thinking it has something to do with CPU usage, like it running a process in the background that disrupts the audio output. But I don't know if anything can be done about that.

[BUGS LIST] Update 4.2.2 - Complete List of Bugs & Issues

According to the thread on the Official Sony Support Community by Lemon and updated by me, Here a thread trying to list all troubles on the 4.2.2 Official Update.
If you're using a custom ROM do not list your problem here because that can be specifically a problem on your ROM.
Gracenote Update
I had approxamitely 3200 songs in my library. I attempted to update the artwork and music info using the integrated 'Download music info' option (powered by Gracenote). This repeatedly fails and crashes, and somehow managed to wipe approximitely 40 artists from my library of 150 artists. I now only have 108 artists, and have lost a lot of music, which I had paid for or ripped from CDs. I now have to do rip these all over again, and I've also wasted a considerable amount of money on MP3s which have now been wiped by shoddy software!!! I just tried to update some more files, just this moment, and while it managed to update beyond 82/800 tracks, it then failed and gave me a 'Network Error' and advised that 2 tracks had been updated - despite that it had already attempted to update more than 82 tracks!!! It's massively buggy. Not going to use it anymore in fear that it wipes more of my library.
Walkman App
Sometimes shows '-1' artists in library. When tapping into the Artist list and coming back out again, this updates and shows the correct number of artists. Why would it EVER show that I have '-1' artists in my library?!?
Android Become Slow
I've had it after the update, if you feel that your android is very slow since the update, just go to the settings, select applications and "desactivate" some useless app that eats memory, be carefull what you're desactivating, you don't need to be rooted for doing that, that helped in my case.
Earpods/Headphones Compatibility
My previous handset was the 2011 'flagship' Xperia Arc. The stock headphones which came with this handset are of a much better build quality (and tangle a lot less easily) than the stock headphones which came with the Xperia Z. However, upon connecting the Xperia Arc headphones to the Xperia Z, I get a message saying 'Headset not supported. Use another headset or visit the Sony Mobile support site for more information'.
Many earpods/headphone seems to not be supported anymore under this update, Sony needs to fix that quickly that's really annoying.
XDA Threads : http://forum.xda-developers.com/showthread.php?t=2340877

MBS-100
Everytime I connect over Bluetooth to my MBS-100 (first generation) my WiFi crashes after about 4 minutes. Every time. This does NOT happen with my MBS-200. Seems Sony haven't put enough effort in testing support for their older devices/products, this is clearly also the case above with the stock Xperia Arc headphones.
SD Card bug surfacing
The Sony Xperia Z is suffering from a persistent hardware failure, which is inserted SD cards unusable. Most of time we need to reformat/restore it and in worst cases the SDCard is dead and you need to buy a new one.
I have this as well that asks me many times to check and verify my SDCARD when i use the MSC connection, if i don't do it i can't copy files on it.

Photo Album uploading with Facebook for Xperia
Tried uploading 31 pictures using the integrated share to Facebook for Xperia feature last night, on a FAST connection (Download Speed: 44.9MBPS / Upload Speed: 7.4MBPS) - 1 picture uploaded, service failed. Tried again, 2 pictures uploaded, service failed. Tried again, notification said 'Uploading pictures for about 18 minutes, before timing out and failing without uploading any pictures. Any pictures that did upload, did not upload in order either. After repeatedly attempting this about 30/40 times, I managed to upload about 17 of the 31 pictures, and had to connect by USB in order to do the rest. Seems like this feature was slapped on without any REAL testing by Sony.
Lockscreen Bypass
It is possible to bypass the lockscreen by typing '*#*#7378423#*#*' and doing an NFC test in the Service Tests menu (http://www.youtube.com/watch?v=LLq1gxIt5YQ) - this renders the handset COMPLETELY UNSECURE.

Socialife
Never updates automatically. Sometimes updates manually. Sometimes doesn't. Just tested manually refreshing this moment, today being March 26th, and nothing is showing beyond the afternoon of March 25th.
Stamina Mode / Battery Life
When first experiencing issues with my handset, a Repair was advised by support staff on the forum here, and official Sony Customer Support Staff. Following this repair, by battery life at 100% showed 4 DAYS AND 12 HOURS. A week later, on 100%, my battery life dropped to 2 DAYS AND 8 HOURS. Another week later, on 100%, my battery life is now showing 1 DAY AND 1 HOUR. All of these figures are with Stamina mode turned on. I haven't added anything to the handset to affect performance, it's simply degrading of it's own accord. Which makes me wonder why the support staff repeatedly assure us on these forums that 'the battery life will improve after a few charging cycles' - this is not the case, and there is CLEARLY a Power Management issue, which needs to be resolved.
LED Notification
Fortunately, I am not experiencing the LED issue that others have been. But it should be listed as others have been experiencing it.
Sleep of Death
Fortunately, I am not experiencing this issue. But it should be listed as others have been experiencing it, special mention for people who hard-bricked their phone, do not include that problem.

Fortunately again, I am not experiencing any major WiFi issues. However, when uploading photos using Facebook for Xperia last night, it knocked off my WiFi twice for no reason. And I've also documented my WiFi issues in combination with Bluetooth to MBS-100 above.
Accessories
The 2011 flagship Xperia Arc came with quality headphones, a charger, and a mini-HDMI to HDMI cable for outputting to HDTVs. The 2013 flagship Xperia Z came with cheaper headphones, a charger and NO cable for outputting to my HDTV. I expected this to be included in the package, given the lofty pricetag, but now I realise I must go and buy an 'MHL Cable' - something I didn't even know existed until after I purchased the device. Thank you for not including this cable Sony.
If anyone has any further legitimate bugs/issues to add to the list above, let me know and I'll keep the OP updated.
If you know a fix i'll add a green comment.

Hi.
I'm on .423 and I don't seem to have the lockscreen bug.
In fact, I cannot dial any MMI codes using the emergency dialer.
On a side note, why is this tagged as [HELP THREAD]? There's already the help thread that I've started under stickies in the Q&A Section.

You're lucky, anyway that's interesting, what kind of ROM do you use?
For the thread i've edited with [BUGS LIST] it was just for being easily found for people, if you have a better idea for my thread i'm open to any suggestions.

Stock ROM for C6603 from here.
[BUGS LIST] seems appropriate enough?
EDIT: There's also this SD Card bug surfacing. I have this problem too.
A bit short on patience right now, so haven't tried fixing it yet. You could add this to the list.
Thanks a lot, SDCard bug surfacing added to the list with critical severity.

I'm Lemon, and these bugs have nothing to do with 4.2.2
I posted this in March, about 10 day's after the handset was launched, listing all the issues I found in the original 4.1 firmware, it's been updated a few times since.
With 4.2.2 I've only noticed a weird support issue where the software completely wiped me sd card of its own accord. I've lost ****loads of stuff as a result. It's only happened once though.
Still noticing the Walkman skipping during playback...
Some Home screen stuttering, nothing out of the ordinary for Sony.
Otherwise, 4.2.2 is much improved.
how are the lack of accessories, notably a mhl cable part of the bugs/issues with 4.2.2 ?
I don't know how to describe it wxactly but since the update (2 days ago), my phone has became super slow.
On 4.1 it was great never experienced any lag.. but now it feels like I'm holding my tired old phone again..
It goes from opening apps, through unsmoothly scrolling and floating around, to the lockscreen it self which can take about 3-8 seconds to show up image from black after pressinv power button to wake him up..
Also for unlocking, sliding up to move from lock screen to home screen can be laggy, stucky, and takes time...
Furthermore, WiFi signal (or atleast the icon showing) is poor and barely reaching my router when I'm 3 meters away..
As for not getting anything exciting from the update, or any changes, cool features from stock 4.2 (hmm som1 said notification toggles?) , I'm pretty disappointed, I would return back if that possible

Yep i've seen many people complaigning about that too, btw you can disable some useless app on settings => applications, select one and choose "desactivate" that's helepd so much for me.
what in the world.. and .423 just came to my phone updates and it's now stuck in the notification bar but seeing all these makes me doesn't want to update it anymore ._.
From last night i am facing a problem where when I connect my headset (samsung) to my xperia z1 it displays the error *Headset not supported. Use another headset or visit the Sony Mobile support site for more information.*
I used to use this headset everyday but unfortunately it had stopped working.
Further, if i use any other headset, it displays the same message.
I have not updated my phone nor have i installed any mod or app.
Can anyone tell me the fix please?
Thank you!!

[Bug report] Music player stops playing music from sd after some time

Hi Omni community.
There is a bug on all Omni ROM versions (i9100 nightlies) related to music reproduction. I have tried many different music players, so it's not an app related bug. The bug is that after some time (few minutes, 10 minutes, 30 minutes - there is no rule) the music stops in the middle of the song. It's not paused, it's just frozen at some part of the song. Even if I kill the player, or force stop it via settings/apps, it will not continue playing the song until I perform reboot. The issue is reproducable in case that you have songs on sdcards, but not if you stream the music...
It seems that sd card is unmounted at some point.

This is almost surely the same root cause as our long standing OpenDelta woes. The 4.4 sdcard FUSE daemon has a habit of hanging on the Exynos 4210 family of devices and we haven't figured out why yet.

Thank you very much for your answer. I will patiently wait for a solution, since I know that the problem is in all KK ROMs for i9100 - seen it on Omni, CM, SlimKat etc.
I've had my phone freeze up or reboot itself while listening to mp3s on an SD card through poweramp. Not often, it's entirely random. I thought it was a problem with poweramp. Interesting.

Initially, I did not have this issue of music stopping at random times with stock Omni 4.4.2 and Poweramp. I started having this issue when I did some undervolting using Gustavo_s kernel and stweaks. Since then I've raised some of the voltages and have not had random music stops. Will report back if the issue crops up again.
I'm having the same problem with my Motorola Xoom 3g. My media file will randomly stop playing n a weird noise will suddenly start. Until I reboot the player will just hang n the screeching sound will continue.

Entropy512: This problem with the i9100 is already fixed?
I want to try this ROM again but wish it was minimally stable, at least as far as the CM 10.1.3 I am using.

Nope, so far I don't know of anyone who has fixed this issue with KitKat on the Exynos 4210 family of devices, and I also don't know why it seems to only affect Exynos 4210 devices.
share the stweaks settings

I guess I should have updated my post with my latest findings, but it seems that my voltage settings "fix" was not really a fix, because I again started having the "music stopping" issue. One solution that seems to be working for now is moving all my music to my internal storage. You can try the same and see if that solves your issue.

perhaps this is obvious and pedantic, but a friend of mine might hook me up with a unopened i9300. I've seen a few different listings of the type of exynos it has. 4212, 4412, 4x12 (whatever that means), etc. perhaps these are typos.
The i9300 is not a 4210 device, correct?

I9100, I777, N7000 (Pretty much the Galaxy S2 family of devices, along with two tablets from the same late-2011 era) - Exynos 4210 (dual-core, 45nm)
I9300 and tons of others (Basically all of the "Galaxy S3" family that contain Exynos processors, including Note2 and Tab 10.1) - Exynos 4412 (quad-core, 32nm, a few internal changes to various built-in peripherals such as the JPEG engine)
An Exynos 4212 exists that is identical to the 4412 except half the cores, which is why you often see 4x12 in code - The Galaxy Gear has this and maybe 1-2 other devices. It's pretty rare.
This seems to only occur on the 4210 devices. My guess is either some weird MMC driver problem that only manifests itself when combined with the fuse sdcard daemon, or a problem in the kernel side of the fuse driver. Thing is the fuse driver is identical to that of the 4412 devices (same kernel) except for whether CONFIG_DMA_CMA is enabled - except their are 4412 devices with CONFIG_DMA_CMA disabled (such as t0lte) that don't have this issue, so it probably isn't CONFIG_DMA_CMA
I'm surprised that this bug doesn't get much attention, as, from my point of view, it makes the AOSP port of 4.4.x completly useless on our beloved device.
Am I the only one who use his smartphone as a music player ?
I've tried many kitkat roms, and was never aware of this issue, because I didnt listen to music while testing the roms. I have to admit this is a bit of a downer, and Im surprised too, that this bug doesnt get much attention. Very interesting.
There is still hope for the S2 ...
gerrit omnirom org 5307
I hope this commint correct the problem so I can start using this ROM.
Unfortunately it seems that Entropy512 is the only maintainer for i9100. We are missing Cody to help... :good:
A guy commented on the gerrit that it seemed it was okay, but he didnt know what to look for. Anyway, looks like it will work.
My i9100 is running 2/2 nightly ATM. I have been listening music for about 2+ hours so far from my external sd-card and I don't have the problem discribed here! Maybe it's already been fixed.
Weird, says on the gerrit it has not been merged. Leave it overnight and tell us hahahaha.

"Music slowing down when screen is off" Thread.

Hello all,
I have researched this issue and have received various answers to this issue, so I thought I would start a thread discussing specifically this topic.
When playing music on my M8, I notice no matter what Rom I am on, I notice the music that is playing slows down when the screen is off.
As if the cpu is clocking in low (my guess is 300) and is slowing playback.
I have found questionable solutions:
1. Wipe data from the music app
2. Firmware update
3. HK adsp firmware.
My device is s-off
Running beyond stock Rom
With the latest Adsp firmware flashed.
Can anyone give me some insight to why or what can I do about this?
i've had this issue too, but i've only tried viper rom. I didn't realize it was an issue with other roms as well. is it a problem with all music players? I've only seen this happen with the google play music app.
Your streaming quality is probably set to low, which can cause this kind of issue. You can change it in the settings menu of play music.
Screenshot of what I'm talking about.
I had the music I was playing downloaded on my device. When the screen was off, my music started skipping.

I was out of town a few weeks ago and this same issue began to happen. It drove me crazy that I couldn't take a walk without having the music sound like it was robot running on fumes. I did a full wipe, re-download and reflashed the Viper ROM I'm using, firmware, played with kernel and screen frequency settings, etc... Nothing I did seemed to work. Until, all of a sudden it dawned on me that it's most likely not a hardware issue and something had to be running when the screen is off causing the music to sound like that. I turned the music channel setting to "Off" and that did the trick for me. The visualizations require a bit of power and the slower cpu/gpu clock speeds when the screen is off sem to d to play a role. Hopefully this is the solution for those of you having the same problem.

Downloaded as in cached or Downloaded as in mp3 on device? I'm guessing cached, if a low quality cached file is cached, I know of no way it'll magically become higher quality...
There may be something to the music channel, but it's unlikely that would effect playback of the file. Mc just gathers info and lyrics and has a visualizer.
I'm guessing you didn't bother to check in your play music settings to see your quality settings, and instead just ignored my suggestion, cause you know what your doing. So once ya figure it out, share with the rest of the class thanks. Meanwhile I don't have the issue and am gonna go back to stream with no lag.

Are you all using a Harmon Kardon?
I have the HK version and have this issue on custom Roms too. My understanding is that its due to having the HK firmware but not the proper sound libs which match it in the ROM, since the roms are based on the standard M8.
Had trouble on:
viper rom
Gpe ROM.
No issue on Bad Boyz rom based on HK.
If you have an hk model and have this issue on viper and perhaps other sense 4.4.4 roms not HK based, they have a mod to flash the libs and firmware, just skip firmware when Aroma asks, since you already have HK firmware
My trouble cleared after flashing it.
Sprint HK
S-on

I'm not currently on viper ROM right now as I installed the gpe lollipop version. I did actually follow your instructions, but I didn't have a control since I've changed roms. And yes I meant cached instead of download. You don't have to be a **** dude, i just gave my experience of having the same issue.
I don't understand why playing a cached version of a song would play slower when the screen is off compared to when the screen is on. Im still have the issue with gpe. My guess is something with some Roms trying to conserve more power when the screen is off.

Here are the results of another test I ran. I played an mp3 file on my phone using Apollo and play music. When playing the same song in Apollo with the screen on and off, the music played perfectly fine. When the same mp3 played in play music, the audio slowed when the screen was off.
Could somebody confirm that this doesn't happen in other music players?

hmm sounds like a cpu is slowing down or something when the screen is off. do you have a custom kernel attached to your rom?
I had the same diagnosis of slow music but due to certain xposed modules that was controlling alarms and wakelocks, try disabling xposed framework to identify if its interfering with any custom ROM framework modification

I am not using a custom ROM just a stock version of Lollipop and am having this same issue on my LG G3. In my case, it's downloaded files on my device as well as cached playback.
The screen being off definitely seems to be a trigger.
I've just started experiencing this with Google Play Music on 6.0 GPE. Did anybody ever find a fix?

I had this exact thing happen on older ROMs as well as the 6.0 GPE. In the past, I flashed a custom kernel and turned on "high quality audio" using Trickster Mod. Although, I've been running 6.0 GPE un-rooted for a while so that's not an option.
Not sure if it is a permanent fix yet, but I turned on the equalizer under the settings menu and I haven't had the slow audio problem for a few songs now.
