Bluetooth problem with Cyanogenmod 10.1

I was just wondering if anyone else was having problems with a bluetooth headset using Cyanogenmod 10.1? The call quality while using the handset is great, but when I use my bluetooth (Jawbone Era, Motorola Sliver Elite) the call quality is absolutely terrible, the person can't even hear what I'm saying.
I say Cyanogenmod because that's my favorite rom, but it also happens on AOKP, PAC, ParanoidAndroid, and pretty much every other Vanilla type Rom.
Any help or suggestions?

The same problem with Jawbone Era. All works fine in Samsung stock 4.1.2 ROM.

Yep. I have this problem, too.
Bummer, as I'm writing a Bluetooth headphone round-up for a magazine this month, and I can't review call quality without borrowing a friend's phone.

Known Issue
Hey guys the bluetooth isssue your speaking of is a VERY well known issue in CM its one of the few bugs that is still being ironed out. Its also present in basically every other aosp type rom because they are all based on CM. The awesome cyanogen devs are working on it constantly and im sure they will get it figured out :good:
So if you here any reference of an "upstream" issue in a ROM thread its most likely referring to it being an issue in CM and therefore the ROM in question. :good:

Bluetooth car connections drops and really bad audio quality when on call.

Hi everyone, I have used PARANOIDANDROID in the past for Samsung Note and had a great experience using it. Just installed the PARANOIDANDROID on my new HTC one.
I am having two issues that are forcing me to go back to a stock rom,.
1st) Bluetooth connection with car, when calling the audio quality is really bad. The person on the other end cannot understand what I am saying.
2nd) when on a call with a headphone /w mic and connected to my Mac, the mass storage keeps going on and off. This affects the audio quality of the phone call.
All other issues that have been reported here I am OK to way for, but the BlueTooth issue forced me to look for a stock ROM for now.
I hope the great the people working on these Rom ( Paranoidandroid and Cyanogenmod ) can fix these issues quickly.

no bluetooth for voip apps
I've tested CM on note I and II, the same issue shows up, I cannot use bluetooth with voip apps. Same goes for 10.2. Too bad

[Q] Bluetooth AD2P Sound Quality

Is anyone else aware of the TERRIBLE streaming quality via Bluetooth? the mids get crushed and sound terrible when I connect my X to my car. Did some research and found a fix for the GNex here:
http://forum.xda-developers.com/showthread.php?t=2184333
I tried to apply it to the X but it turns out there's no bluetooth-default.so in the system/lib/hw folder ... only a2dp.default.so
I replace just a2dp.default.so with the 'fixed' ones from that thread and then my phone wouldn't hold a connection to the car (Gmusic kept telling me "cannot play requested stream") and when I toggle off/disconnect from bluetooth my phone would reboot.
anyone got ideas for a fix?
there is a directory called bluez-plugin and inside that there's an audio.so and a bluetooth-health.so but I dare not mess with them hehe.

I haven't noticed poor quality streaming at all... I have used it a lot.

The Moto X doesn't use the AOSP bluedroid stack, they stuck with Blue-Z stack so it doesn't have the same problems, and you can't apply the same fix (as you discovered).
My experience has been 100% positive with Bluetooth audio on this device, it sounds just as good as the fixed AOSP bluedroid stack does to my ears on all my BT receivers. I don't know for certain but it's pretty likely that the Blue-Z stack Motorola used is newer than the last one we saw in AOSP (Android 4.1) and there is probably an incompatibilty with your car if it really sounds that bad.
Before you guys jump all over me and call me an idiot ... I happen to be the guy that came up with that particular fix for the AOSP bluedroid stack in the first place :silly: (http://code.google.com/p/android/issues/detail?id=39632#c151) <--- woot! I'm this guy! LOL, whatever, I know. What the fix essentially did was set the bitpool (like a buffer) to the recommended size for high quality audio, but modern Blue-Z implementations didn't suffer from the same problem. It was introduced with AOSP Android 4.2 and persists in AOSP Android 4.3.
Do you have any other A2DP receivers to test against at your disposal? I've used my VZW Moto X against a Rocketfish Receiver (http://www.rocketfishproducts.com/products/home-theater/RF-BTR212.html), an HDMX Jam (http://www.hmdxaudio.com/jam-classic-wireless-bluetooth-speaker.html) and most recently a Bose Soundlink Mini (http://www.bose.com/controller?url=...s/bluetooth_speakers/soundlink_mini/index.jsp) -- playing as I write this post -- it honestly sounds just as good as my fixed Fascinate and my fixed Galaxy Nexus did, perhaps even slightly better!
Moto X A2DP = djp952 certified! :victory:

I have the same issue with poor sound quality when I stream music to my 2013 Subaru Legacy stereo. The problem seems to be that the sound is overly compressed and when a lot is going on it becomes especially noticeable. Part of the issue revolves around devices that don't support the newer APT-X codec, if the device supports that codec the sound is said to be fine however any device that uses straight A2DP will experience this issue.

I have had the same experience as you. I have tried my Moto X with about 10 different bluetooth receivers. I have had nothing but excellent sound quality.

I'm experiencing the same crappy BT audio I was with my galaxy nexus prior to your fix (thanks a lot BTW) on my moto x with the same BT receiver in my car. I've got a couple others I will try and report back later.

Moto x doesn't sound good on any BT device I have but none of them support apt-x which the moto x does? I know the rocketfish you mentioned has apt-x but not sure about the other 2. If they do maybe that's the difference in sound quality?

I'm not sure either It's a good bet the Bose one does since its brand new. Seems like a pretty good theory!
I think I still have a really really old Scosche receiver kicking around somewhere I can try for you guys and compare it with an AOSP bluedroid-based phone.

http://www.csr.com/gogroove-bluesync-portable-bluetooth-speaker
Forgot to test on that which does have apt-x though I don't think it specifies in the manufacture or amazon site but that's the actual apt-x website. Can confirm that it definitely sounds better than my other devices.

Some Test Info if it helps
I have the same audio quality issue with my VZW Moto X, constant crackling noises, but I only experience it with one bluetooth receiver (of the ones I have available to test). Unfortunately, it's the only one I have built into my primary vehicle, so it's extremely frustrating. I don't have any data that indicates what these products support in terms of codecs, but here is some info if it is of any use in diagnosing the problem:
Pioneer DEH-X9500BHS - Works Great for BT-Audio and Pandora Mode
Satechi Soundfly View - Works Great
iSimple Connect ISHD651 installed in a 2008 Honda Accord - Worked Great with my Droid Inc 2, but horrible crackling with my Moto X.

I don't see any indication that states that deck supports apt-x. I read on the android bug report page that one user running 4.4 claims they've finally fixed this issue so I guess we wait for 4.4 now.

The deck does NOT have to support apt-x in order to sound good. The moto x is the best sounding bluetooth device I have ever connected to my deck, and my deck for sure doesn't have apt-x. I am so up tight about sound quality that i've always used a cable to connect my devices. The moto x is the first device I have used where I no longer need the cable and have thrown it in my closet somewhere.

My Bose Infiniti head unit sounds amazing streaming Bluetooth from my wife's iphone4s and a load of rubbish while streaming from my motoX.
I'm very close to just saying screw it, giving in, and buying an iPhone.

Tips for Xperia (v) owners with incompatible headphones

Hello all, I need to post 10 messages before being able to post one useful reply in the development part.
Having no idea what to write about, I just transform my (unpostable) answer in a useful thread where more people will find it and where i might even get useful reactions so that we all learn some things.
Ok, to the point:
When using most unofficial headphones, the telephone won't recognise the plug layout.
Depending on the rom/firmware it hasn't got the same consequences.
Sometimes there is sound coming out of the headphones and sometimes there isn't.
With the official Sony roms it wasn't a problem before (just a popup message stating the buttons unavailable) but I had the no sound problem on my V after updating to 4.3 too.
I have an xperia v and before that I had an xperia p, an app called SoundAbout has solved problems for both models, with all kinds of headsets and every rom, both on dalvik and art, so it might work for other models too.
I found it here on xda frontpage a few years ago and it never let me down.
I'm not affiliated with the creators by the way.
We got a free licence for the pro version here ont the xda forum at the time but I lost it and the free version does just fine.
It really is very simple, you start the app and redirect media sound to the headphones.
Another thing that I discovered only last Sunday:
The disadvantage of the SoundAbout app is that the phone considers the outgoing sound as going to the phones speaker, and thus a lot of audio enhancements like headphone surround don't work, you only have the options for the speaker that will have effect.
But I'm running a new rom now, 4.4.4 neowave, the fastest and best battery by far of all roms I have tested.
This rom uses viper4android, where i found an option to lock the settings, so that it is possible to use the headphone options on the speaker sound, and thus for the headphones when used with SoundAbout.
I don't care about mic or buttons working so I have no info about that.
But the sound on my v is finally perfect with my highend headphones, after years of searching how to.
I hope this helps someone, and that it makes other people as happy as I am.

Comon peeps, more than a hundred views but not a single reply?
I don't want to make a 10 post monologue to get to the limit of being able to feedback in rom topics....
Doesn't anybody care about sound quality on his phone ?
Are people getting used to choppy badly decoded music that much?
Am I unique in carying and listening my music on my phone?

I just want to drop by and say that this works indeed for all my NeoWave users, Xperia T ones included.
So if you have any earphone issues, try this app! :good:

Thanks for dropping by
I'm glad it works on the T too.
Personally I tried almost all roms for the V that are/were available here on xda, I haven't counted but that must be more than 20 roms, not counting the updates, and SoundAbout always worked.
For my P also I tried a lot of roms and mods, and no problems encountered with SoundAbout (a lot with incompatible headphones on official roms).
It seems that it is not guaranteed that the mic and buttons work, even with the pro version that has more options, at least that is what I found reading around on the Web, but I'm quite curious about the actual pro version.
Is there anyone that has experience with the pro version ?

I have not tried the pro version, but I have another question..
Do you have any experiences concerning the trial version? Is the usage limited to a certain amount of days or does the app provide most of its features for an unlimited amount of time?

Concerning the media sound routing there is no limitation.
The free version has the following options :
Service - on(background), on(foreground) , on(auto restart), off
Media audio - let app decide, speaker, headphones, headphones (with mic)
Notification behaviour - block notification to speaker on/off
Notification behaviour - block ringtones to speaker on/off
Notification behaviour - speak caller name options
Wired headset behaviour - set detection options when plugged in
In the pro version there are
Phone call redirection settings
Extra settings for text to speach
Bluetooth behavior
Dock behaviour
So, with the free version the headphones do not work for phonecalls.
As I already don't use my headphones for calling, it does not bother me.
hat does work is the widget (1 tile) that toggles sound redirection.

That's great. So the functionality we need is not limited. :good:

It's not work on my T

What exactly does not work?
It won't autodetect some headphones but if you set service to "on, foreground" and the media audio setting to "wired headphones" ?
Isn't there any sound coming through ?

Is there maybe an app that will make my Xperia V recognise my Nokia (TV Out) RCA cable?

If the jack has a standard layout, it will work.
Not sure that it will recognise it automatically though.

Nokia MD-310 Bluetooth Receiver issue

Hi!
I'm loving my new Z3 Compact but ran into first annoying issue. I've been using Nokia Wireless Receiver to stream audio via bluetooth to my amplifier. It has worked well with my previous phones, iPad Air and also my wife's Galaxy S4 Black Edition that has KitKat installed.
With Z3 it connects and phone shows aptX device connected. Audio starts playing but cuts off and back constantly, almost like it loses connection every half a second or so. Tested Spotify and Radio FM to make sure it's not an app issue, same thing happens with both. I also got JBL Flip 2 speaker and bluetooth audio is crystal clear with that, no issues at all.
I'm a bit baffled because it doesn't seem to be an Android issue (Galaxy S4 working well), not an app issue and also bluetooth audio from Z3 works with other devices. Any ideas/help would be appreciated.
Thank you.

Hi. it seems like you and me are having the same problem except I have a z2. Previously I had a Xperia sp and that works fine with the Nokia receiver which leads me to believe it has something to do with aptX as my z2 works OK with other non aptX devices aswell.
Did you ever find a solution to your problem? I found that if you turn WiFi off it helps a little, but is still un-listanable to my ears

Yes, for sure, but we should enjoy the last oreo days No reason to root this phone. It's up to date, more than my other devices (Z Play with Pie on 5.10. patch, P8 Lite 2015 with Nougat on 5.09.(with custom roms, no official support anymore)). And Pie is coming very soon. Great phone ?

There are various reasons to root this phone.
(Mainly 2 for me)
1. Enable the Audio Offloading
2. Use Viper4Android Fx
3. Use Adaway
Other optional uses also..
Also some weird issues like only headphone (w/o mic) icon in status bar when using earpods..
I have to currently use Moto Z (running LineageOS 15.1) due to this and tired charging it 4times a day. It seems i have to wait 1month more for Pie and hope these issues are fixed

You are right, biggest problem is audio over usb-c, that's why I'm using a bluetooth headset. And now the sound is strong and good. But that's not the perfect way, every 6h the battery of the headset are going down. I would more like to get good audio out of type C. But it's ok with bluetooth. I have JBL.
Yes, I'm doing much with the Z Play, the most of all. There is no other good way to using Pie now

I too have a JBL T110BT headset apart from the battrey dying in 5-6hrs it doesn't have a strong base and qlty like mine weird Sennheiser and Earpods. I tried using the Viper , only i can get is 44Khz sampling rate (compared to 48khz) , no Playback gain , apart from that i cannot change mine codec from SBC to aptxHD. Can you plz tell me how to use aptxhD or does it depend on the BT device..?

Here it is an JBL tune 205bt, maybe almost the same.
And don't know, here I can't change it, too. Maybe just for certified bluetooth devices? But sound on bluetooth is here really great, much better as on type c. So, it's really good enough. Better maybe just with very expensive headsets.

Hi man, can you explain to me how you "Enable the Audio Offloading" ?
I'm already rooted. thanks

What's the best and easiest way to install the update when rooted? Obviously OTA's do not work for me and i'm "stuck" on the September patch...i'd like to update to the newest.
