USB-OTG External Soundcard - Xperia Z Q&A, Help & Troubleshooting

Hi there iam trying to use my external USB-DAC (Audioquest Dragonfly) over the USB-OTG Connection and so far i atleast achieved somehow to playback tracks using "USB Audio Player Pro Trial & USB Audio Recorder Pro Trial" but iam facing some serious problems while doing so.
If i activate the lockscreen(pressing powerbutton) to turn the display of, i can't reactivate it anymore, it keeps playing the music but the screen doesn't turn on again.
After 1-2 Minutes it reboots itself without asking for the PIN etc...
Anyone else facing those issues, and is there a possibility to use the external Soundcard without third-party apps?
How about the leaked 4.4 build? I heard USB-Audio is fully functional in 4.4 without third-party apps.
Thank you

[Q] Bluetooth: phone calls work but music won't

Hello,
I rooted my LG P990 and installed JMCyanBreadMOD, and afterwards the most recently nightly (CM51) of that time. Before one of the CM installs, I could make calls and listen to music from my phone over my car's audio system. After the CM install(both of them), only calls would function.
When I request bluetooth music in my car, I see the media player is launched, but that's about all that happens. It seems to be kept paused. Explicitely pressing play to have it continue playing doesn't help either,I see the time bar moving, but hear nothing.
The CM's bluetooth settings for the connection to my car's audio system are set to be used for phone and media.
I'm wondering, since calls do work, perhaps I missed some setting somewhere ?
Or is it something that simply isn't fully developped ?
Somebody got an idea ?
Many thanks

It doesnt work with cm7 yet. Try modaco if you really want/need it

Hi, make sure your Bluetooth support A2DP.
However, if your bluetooth heatset doesn't have, you can try this: http://forum.xda-developers.com/showthread.php?t=649059
I don't guarantee it work or not, however, NvFlash is always there for you. ;P

Pebble interfering with bluetooth playback?

Hi peoples!
I recently got my pebble and installed the app, but since I installed the app I've noticed something odd with my phone. When any bluetooth device connects, media playback will switch from the speakers to the earpiece, and bluetooth headsets wont play/control music anymore. When connected to wired headphones itll play, but the default audio buttons will change the call volume, not media. After 10-30min it reverts to how it should be...at least until a new bluetooth connection is made. This persists whether pebble is connected or not, or if the app is installed or later uninstalled. Is this something to do with the pebble's connection to the phone, and if so is there any way to fix it? I've tried a full system reset on the phone and it's good for awhile, then changes again. Is it possible to just reset the audio drivers?
For some background information, I'm using a Galaxy S4 (Verizon) running 4.3 and no custom/root software. Both the Pebble app and firmware are up to date (as of 12/10/13), and accessibility services are turned off.
I'd appreciate any help I can get, thanks in advance!
What media apps are you using? Some apps such as BeyondPod have a setting on whether they send the song info to the bluetooth device or not...turning this setting off will correct some issues.

I got my Pebble two days ago and I've used it twice so far in my car with no problems. I use a Bluetooth receiver which I plug into my cassette adapter since I don't actually have a car system that has Bluetooth. I've also been able to control the music from the watch with no problems. I use a N5.
I got a N4. No problems over here. I would look over the settings of whatever apps you use! And play around with those.

Weird problem with speakers and mic

I have a problem with my unrooted Xperia Z with a locked bootloader. My main speaker does not work for any media like music games or videos, but works fine for loudspeaker calls. Also the earpiece speaker doesnt work at all. Another problem i found was that my microphone would not work at all unless it was in a call and i was using loudspeaker. The final problem is that when ever i plug in my earphones, google now pops up and sometimes my phone starts playing music automatically throught the earphones, when i remove the earphones, instea of stopping the music continues but the speakers dont work so it just keeps playing them silently. If anyone knows the soultion to this, please respond as ive searched everywhere and i have not found one solution yet.
UPDATE: i used the application soundabout to reroute the audio and the calls are now fine, the only problem is that when i plug in my earphones the google now problem persists. If i plug in earphones with a mic, i dont get any of these problems and everytime i want to use my internal speaker for media, i have to manually re-route the audio to them. Anybody know a solution to these 2 problems?
I do have the exact same problem, I tried different ROMs and Audio Mods (at the moment I've got a stock ROM) without any change.
Did you somehow fix it?
Exact same problem, i run stock android 5.1.1 build 10.7.A.0.222 locked boot loader. Problem suddenly came up last week during vacation, quite some time after I did OTA upgrade to 5.1.1 - so this is not related to ROM updates.
After installing soundabout (thanks for the hint) the rerouting did not work immediately - i had to set phone to earpiece and media to speaker in the app and reboot for it have an effect.
I think the root cause is, the phone thinks there are headphones connected, when there really aren't. If I use the UKW radio app, it starts and shows headphones as output-icon right away - it should actually complain that there is no reception without phones because the antenna (headphone cable) is missing. Since it doesn't complain I guess that's the culprit.
Any hints how to fix that, without using a rerouting app? (kinda stupid, using bluetooth speakers and so on now needs a manual setting change in soundabout).
I have that phone for more than 2 years now and used headphones maybe twice with it, so a busted headphone-jack is out of the question too.
Guys give it a try.
Thanks Ess Arr, that really works!

Audio, media, microphone problem

Currently I'm using my Moto XT1058 as my daily driver, about a month ago I've had a problem with all my audio, recording, and media. I'm not sure if a faulty headphone jack would cause this problem.
About 1 and every 15 boots my speakers and media would work. And the microphone to my (I believe my bottom default microphone works(The one that uses the Google Keyboard Auto typing). My headphone jack wouldn't work, my earpeice, and speakerphone mic won't work. It will remain this way until the next reboot.
However about 14 out of 15 reboots... All my audio will not work. Nor any of my media. When I say that I mean I am not able to play a song without my phone giving an error. I am also not able to play any video (YouTube or any web video) without my phone giving my a playback error (That's why I say I do not believe a faulty headphone jack would cause this problem. I thought it would have something to do with the software, but apparently after a reflash to stock I am still not able to get it to work properly. This issue will continue until I reboot it a whole bunch of times and it decides to work one time again.
Sounds weird doesn't it, not sure if there's any fix, but I post here to give if a try to see if anyome could help. Phone doesn't have an unlocked bootloader and never has. It is SIM unlocked (bought it off of eBay while back) I've already tried rerouting the audio problem with 3rd party apps like SoundAbout.

I have the same problem no audio from speaker... Headphones or Bluetooth I also get an error trying to play videos

Audio via Bluetooth stuttering - unusable

Hi all,
The same headphones which used to work perfectly with my Huawei Honor 8 stutter upon Bluetooth music playback to the point of unusuable. It's the kind of stuttering like there's a poor connection/bandwidth issue between the phone and the headphones. It's similar to what happened on my Huawei Honor 8 when I was washing my car and ducked my head under the car
Tried multiple apps:
Google Play Music
Youtube
Youtube Music
Amazon Music
EDIT: ONLY my Philips SHB4405 headphones suffer! Tried different bluetooth devices to eliminate the headphones, same stutter.
Tried setting the special access to the battery use: "Settings", search for "Special access". Select "Ignore battery optimisation". Make sure "All apps" are shown. Select the app you want and set it to "Allow (May drain your battery more quickly)"
Tried setting Battery settings of the app to manage manually then Auto launch, Secondary Launch and Run in background all toggled on.
Any ideas please?
It is likely their hyper-aggressive battery management software, which there seems to be no way to remove.
You may try to go to development mode menu and play around with the BT audio bit rates and codexs. Or, just take it back to the shop and exchange it for a new one.

I wish they'd just use STOCK ANDROID. who the hell do they think they are to think they know better than Google about it's own OS!!! very cross
try turn off WiFi ! - > WiFi + Bluetooth = stuttering

I'm using my phone with two BT device, one is a Jabra device I have in my car, the other one is the Backbeat fit from Plantronics. Honestly say BT communication works very well. EMUI 8.1.0.161 (C432)
Any update available for download?

funnily enough I did have an update apply yesterday but it didn't fix this behaviour. EMUI 8.1.0.159 (C782)
I have an update to my OP though. The bluetooth music streaming actually works perfectly on every bluetooth audio device I have (Radio, AV receiver, 2 x car stereos, bluetooth speaker, another set of bluetooth headphones) so I can only assume that the Huawei P20 Pro is incompatible with the Philips SHB4405 headphones! sounds bizarre to say it but that's my experience!
Bluetooth codec fix
I fixed this on my Honor 8x by changing the bluetooth codec used in the developer settings.
1. Enable developer settings
2. Change the "Bluetooth audio codec" setting value from "aptX" to "SBC"
Hi mate, check the supported codecs on your headsets. Enable developer options in Settings and force SBC codec.
Has the latest 9.0 solved your Bluetooth problem?
I have the same issue with Bose and Jabra headsets... Cheap chinese BT headsets Line taotronic seems to works fine.. I have given up trying to figure out the cause... Thing is I love the p20 Pro but this BT problem is really annoying!

Hi Guys,
I have a P20 and I love it, but had the BT audio stuttering problem in my car for a while - the radio is fine, my gf's Samsung can stream to it no problem.
9.0 didn't help, the problem persisted until... I changed the display sleep time to 10 minutes and forgot about it.
So after some testing I can 100% confirm that the stuttering happends only when the screen is off.
When I drive with the screen on, the BT music streaming works great. When I turn off the display - within minutes the stuttering starts. Turn on screen again - no stuttering.
Test it.
Happens on my Mate 10 only when screen is off. I already removed PowerGenius and had set battery optimization off to my music app. This is so annoyingly frustrating. Any solution yet?
I think I have the same or a similar issue using Beoplay H9. Changing codec to manual SBC or AAC does not work, but SBC is noticably better.
Closing all open apps or restarting bluetooth often works, but restarting the phone completely alleviates the problem. After an hour or two the problem appears again.

Can you check if the headphones are paired to anything else in the vicinity? Like a tablet or other phone? May be the problem..
Also the codecs in use make a difference too, can be altered in Dev options.
I had problems with calls with a very expensive pair of plantronics on my phone, the v6200's £275 when they were released lol.
Base didn't make a difference either Oreo all the way up to 9.1, in fact it was better on Oreo.
Doesn't affect everyone in the same way.
Paired to stuff yes but I can take them out of the question by wandering away from any of the devices for a 1-2 mile walk
Still experiencing this same problem on EMUI 9.1, even after disabling battery optimization in all music apps.
This worked for me - turn off 'Always on Display'
I was getting brief but regular strutters with my bluetooth headphones (Marley Positive Vibrations 2) but only when the p20 pro was put in my jeans pocket, so walking the dog while listening to Spotify was a pretty glitchy affair. At first I assumed being inside the pocket was degrading the bluetooth signal strength but I recently noticed that whenever the phone sensed it was inside my pocket (or in a pitch black room) it was turning off 'Always on Display' to save battery, so wondered if this was affecting the bluetooth audio connection (especially as people already suggested it was related to either display settings or battery saving options).
I disabled 'Always on Display' and this stuttering problem has been completely resolved for me (EMUI 9.1).
@theToots
Where to find the option 'Always on Display'
edit:
Found
I have this same Issue using a P20 Pro and Sennheiser HD 4.50 btnc.
This annoying audio stuttering started happening only after a software update (EMUI 9.1.0.361).
A fix that works for me is to turn my location off.
