Bluetooth A2DP problem -- not playing through headset - Nexus 4 Q&A, Help & Troubleshooting

Hi folks, I've been having this very frustrating problem with A2DP that I can't seem to find anywhere else on the forums.
My bluetooth headset (Nokia BH-905i) connects to my nexus 4 just fine, and I've been using it to listen to music since I get my nexus in january. But recently, every time I connect my headset, and I go to play any music or other sounds that play through the media channel, it comes out the speaker on the phone. In addition, when I use the volume slider I get the "speaker" icon instead of the "bluetooth" icon that I used to get.
My bluetooth headset has worked fine since the OTA update, it's just very recently (last week or two) that this issue has been happening.
The first time it happened, a simple reboot would fix it, now I can reboot and re-pair the headset all I want, it just won't work.
Has anyone else had this issue?
PS. I will also add that the next/previous track buttons still work, but the play/pause button DOES NOT! Very strange!!!

Am I seriously the only one with this problem?

What music player app are you using? That could be the problem right there. I sometimes have this problem with my JVC Arsenal head unit, but usually disabling and re-enabling bluetooth does the trick. Don't have to unpair or reboot, just toggle BT on and off.
Anyone know how to get the track info to transmit? It used to work with Apollo and Pandora, but it won't work with Spotify or anything else. In fact, it doesn't work at all on the N4

I use DSub, but I've tried google music, and also any other "media" sounds don't go through the headset as well ie: Youtube, games, etc.

have you checked the device profiles in the bluetooth menu? there is an option for phone audio, and an option for media audio, check them both

Yes I'm sure, I've also toggled them multiple times to try and get it working...

I also have this same problem. I'm using CM 10.1 nightlies
For some reason I able to pair my phone but not the audio.
In the Bluetooth settings though I only have the option for phone audio and not media audio. After checking on a couple of forums, it shows that my radio does support Bluetooth streaming through a2dp, but for some reason I cannot get it to work on my phone...
Edit:
It seems as though A2DP is broken in CM 10.1 as in stock android roms. I'm not 100% about this, but thats what it looks like.

Hi,
I do use AD2P audio a lot, and never had this issue (Sony MW1).
I m using exclusively AOSP or AOKP based roms (never use stock CM 10.1 because of how silly big is the navbar), but I can give it a shot during my next flashing session for testing

I don't have any problem pairing the audio. The checkbox goes and the headset actually beeps. It's connected, android just isn't sending the audio to the headset.

Me too

I've got the same issue.
I have tried with both jawbone and jabra headsets, no joy.
If I toggle bt on/off/on, connect the headset and then try playing music immediately I get ~1 second of audio over bluetooth before it goes silent.
I'm currently on PA 3.15 with moles kernel, but am going to try some other kernel/rom combos.
if anyone knows which logs i should be looking at i'm happy to upload them

Not quite the same problem, my music plays out of the phone speaker. Also I'm running stock rom.

If i wait more than 1 or 2 seconds after connecting my headset it comes out of the speaker also, as the bt media connection dies. I only get the little bit of audio if i hit play right after I connect the headset

I managed to find a very strange work around...
I installed this app: https://play.google.com/store/apps/...sImNvbS5tYXhpc3Rhci5tb25vYmx1ZXRvb3RoZnJlZSJd
I turned on the app, and I could listen to music over mono mode (which sounds AWFUL). I then turned the app off, and when I changed the volume with the volume buttons I noticed the volume bar was displaying the bluetooth icon instead of the speaker icon.
My app was playing music, I didn't hear anything, but my headset was still outputting the characteristic 'hiss' of being in mono mode. So I went into the bluetooth settings and turned off mono mode, and now it is playing music through A2DP finally... We'll see if this problem occurs again and I'll see if the same process fixes it again. I'm just glad it's finally working again without resetting my phone.

I just wanted to update my post for anyone else who might have this problem in the future. I've performed this fix once before my last post and I haven't had to do it again, I've also uninstalled that app and everything is still working great.

It worked for me too!
Thanks to PickleHead and his workaround I'm listening again.
Thanks!!!

Media audio VS. Call Audio
Hi,
I have Samsung galaxy S3 with android 4.1.2 connected to my fordAudio BT device.
I am playing music using the original media player that came with the Android.
The BT connects quickly, but I can't hear the media I'm playing.
Recently I have discovered a "workaround":
When I disable the "call audio" (using the BT menu in settings) and leaves only the "media audio" checked, I am able to hear the media play.
If I re-enables the "call audio", the sound mutes immediately.
Does this helps to understand the issue?

I'm having exactly the problem described here, but this solution doesn't work for me. I have a Galaxy S4 and the bluetooth media audio sometimes works when I boot the phone up, but later it doesn't work. I tried this MonoBluetooth app and it doesn't seem to help. When I tell it to turn on the the mono signal, it says the media is disconnected even though the bluetooth module says it is connected to the AD2P device with media audio. On cases where it does connect, it seems to work, but in that case the bluetooth works with out this app fine.
I'm running 4.2.2 and see this on both the MDK and ME7 code base. I'm looking for a good soluton. I tried the Bluetooth Fix Repair on Google Play, but it can't seem to find my bluetooth configuration folders.

I have had exactly this problem for a couple of days with my S4 connected to my Jabra Freeway car speaker. Also in my case, disabling call audio makes the music pass through, but then I can't use the phone via the speaker which is sort of the whole purpose of the thing!
But I just found a simple workaround: I simply called my phone from another phone to check that phone audio passed through with both options enabled. It did. But it also cured the problem: After the call, media audio worked again - with both options checked.

I'd be interested to know if this fixes the problem for any length of time. Occasionally, and usually after a reboot, I can use the media audio, but then it fails when I try it again. Fiddling with the connections and apps sometimes makes it come back on, but usually only for a short while. While it is connected, it seems to stay connected.

Wireless Stereo problem on 8125?

Hey, humans!
After searching through the forums for a couple of days, I thought I would go ahead and post to ask if anyone has a fix for the following problem...
I recently purchased the Jabra BT 620s stereo Bluetooth headphones, tapped the A2DP cabs, and got wireless stereo working (along with all of the buttons and the mic) right away.
Unfortunately, every time I turn off the headphones and reconnect them, they connect to the phone as "Hands-Free" only. In this state, I can use the answer/call/play/pause/etc. buttons and the mic, but audio is delivered through the 8125's speakers and not the headset. To fix it, I have to open the BT settings, click on the Jabra phones, Refresh (because it still says that the set is connected as "Hands-Free" and "Wireless Stereo"), and reactivate "Wireless Stereo" every time I want to listen to music.
Is there any trick/registry tweak that could help me bypass this extra step? Oh, and does anyone know of a media player that doesn't hog my resources like WMP, uses AVRCP, and can play streams?
Thanks in advance!
In response to my own (2nd) question...I've read that TCPMP respondes to AVRCP commands.
Does anyone know how to get them to work with the Jabra BT 620s headphones?
I'm continuing to look for a solution to my problem and find an alternative to WMP10, which sucks up so much memory.
I have finally managed to get Pocket Player 2.72 (http://www.conduits.com/products/player/download.asp) working with AVRCP. Although it is supposed to work right out of the box, I tried using it and received no feedback from the Jabra BT 620s's buttons.
While looking for a WMP today plugin -- one that I had hoped would have a smaller footprint while still allowing AVRCP controls to function -- I came across a post and eventually found a .dll for Pocket Player that allows me to use my Jabra's controls to influence the player.
Unfortunately, Pocket Player is a woefully bad player (even worse than WMP10 in my opinion!) and I can't get much use out of it because it “skips” constantly and forces the screen back on (it doesn't automatically shut off again) with every command from the headphones. However, for everyone who prefers PP and can't get Bluetooth to work through it, trying downloading this rar file (http://www.modaco.com/index.php?act=Attach&type=post&id=19163), unrar'ing it, and placing the enclosed .dll in your Pocket Player directory.
I personally really like pocket player, but you need to wait for v2.73 out soon apparently. If you go to conduits forum you can see alot of info on this issue.
I find it plays beautifully thru iTech Clip R35 (I admit I have a different device ie jamin).
But to your first point, I still have that problem as well, I have to manually switch on the bluetooth stereo option, I haven't found a solution for that yet.
cheers

Hi, I just bought the BT-620s and have exactly the same problem you have mentioned, otherwise a great BT headset.
Did you ever manage to find a fix for this problem?

Getting Bluetooth to work for music...

I switched from a Blackberry to an HTC TD2 and now am not able to walk around stores with music running through my Bluetooth. Is this a known problem with HTC or am I missing a setting. I looked everywhere and didn't see a setting that changes. Also I'd like to be able to watch Coreplayer with a Bluetooth but, just like music, I hit the button to activate Bluetooth, I hear the sound, and 3 seconds later it reverts back to speaker.
is there a fix that would help me?
FTR: I know Bluetooth Headset is not optimal for listening to TV or music but I would like to do it anyway.
I have multiple Bluetooth and none of them work for this purpose.

Bypass A2DP on demand

I have this issue with my HTC BT Headset which when paired and connected will receive all sounds including games and system sounds. Sometimes even the ringer will only sound in the headset and not on the phone (this happened at rare occasions).
I have edited the settings of my headset and unchecked the option for media but then it comes back again when I connect again.
Now, I want to be able to divert audio back to the device when for example I play a game or play a media clip. The only thing I see on the screen in the message that audio is being played on the BT headset.
I am sure there must be a key sequence to bypass this but I can't figure it out.
Sorry I have no solution, but just to say I have similar issues. My HTC headset picks up the audio from Copilot.... which I suppose is no bad thing in itself, except that the sound drops out all the time... which is pretty useless on satnav! Not sure whether this is a problem with the phone or the headset (whihc is otherwise working fine). I'd just like to switch off the A2DP feature too.

Problem with bluetooth/Music

Hi
First i have to say is SORRY about my english. I'm learning and i don't want to use a translator.
I have a Nexus One connected to my handsfree on my car. I have a Ford Focus. Well when i try to listen some music on it, stock music player star to play and stop, start and stop anbd i don't know why.
I have flashed many times OxygenN1 mod and for all other things the rom is perfect but i don't know why do this.
I have to say to, if i try to play music with another app it starts to play normaly while stock player is playing on the buttom so this is imposible to listen anything.
Thanks for all.
Anyone can help me?
Thanks
All I can contribute is that I am having the same problem.
I am using a Bluetooth headset to listen to podcasts - this is one of those headsets that supports the A2DP profile for playing music etc., as well as the normal headset profile for phone calls. I don't have the problem when taking calls, just when listening to music/podasts so I suspect a problem with the A2DP profile implementation.
You are probably using that same profile in your car.
I wasn't sure if it was the phone or the headset that had the issue - sounds like it is probably the phone if you are having the same issue.
For the record, i have the AT&T/Rogers Canada version of the N1, with 2.3.6.
A couple things to begin troubleshooting:
1. Try using your phone with a different vehicle. It would be helpful to try pairing your phone with a different car's Bluetooth stereo, and see if it works properly (maybe a friend with a recent car?). If that works, then the problem is with the car stereo.
2. If you have a friends with other smartphones, try having them pair with and play music through your car stereo. Hopefully a pattern would emerge: maybe your exact ROM doesn't work, maybe it's a hardware quirk in your phone itself.
3. What media players do you have installed? I occasionally have conflicts between players fighting over the Bluetooth connection; Pandora and the stock player used to fight, but now they play nice. Notably Pandora has a section in its settings that tells it whether or not to take over Bluetooth controls. This sounds like it might be the reason for your second problem (if I understand you correctly).
4. You might also want to try a different firmware, maybe one that's either closer to stock or further. Maybe try the stock firmware first, then maybe MIUI.
5. What year and model is your Focus? Sometimes (rarely) there's a firmware update for the car stereo.
If the stock player is starting and stopping by itself: first try uninstalling all other media players and see if it still happens. If it does, it might be that the car stereo is sending pause keypresses, which it shouldn't. There might be a defective button on the stereo, or maybe a quirk in the stereo firmware.
Hopefully some of this helps narrow down the problem. Let us know if you get any results, hopefully we can help find the problem!

Are you using the headset for both podcasts/music and taking calls? Or using the headset for part of it, and another Bluetooth device for the other?
I just ask because I once tried leaving my voice-only earpiece for handsfree talking while listening to music over the car stereo. I had them "working" configuration-wise (the earpiece took only calls, music went only to the stereo), but after a little bit the phone would sort of melt down and lock up. It was probably running turn-by-turn Nav at the same time that did it, still it was cool while it worked
There are certainly bugs in the A2DP and AVRCP profiles, but I understand the implementation is kind of complex and there's a lot of corner case problems. Personally, our stereo displays the artist & album names, but always says "Paused", and the title and time info and just random numbers.
About the best you can do is try to isolate your specific problem, then try to find where to file a bug report. CM is probably the most responsive but most resource-strapped for fixing corner case problems, Google is at the other extreme and never really replies to bug reports. The stack itself is written by the BlueZ group (which I can't link, you'll have to Google); I've never tried submitting a bug report there, as I suspect they wouldn't be interested in hearing from a 3rd-party Android ROM user.
This might sounds odd, but try turning wifi off and see if that solves the problem.

try downloading ES Explorer (this has a player built in) browse to the audio files and select play in ES media/audio, I could get music to play through this but not the stock player because it would keep stoppping after a second or two.

[Q] Play music thru BT while Headphones plugged

Scenario I'd like to see:
Wired Headphones plugged in
Bluetooth connected to audio receiver
Music plays through audio receiver
Calls go through wired headphones
If a call comes in it pauses the music app and transfers audio to headset. As soon as call complete music continues.
I can get this to work on my Scotts Clean Rom Note 2 and iPhone 5 fine but I can't seem to find a setting or app that can allow this behavior.
Why?
I much prefer hearing music through my car speakers and if I get a call it's much easier to hear and talk through the wired headset.
Anyone else have this use case? Figured out an answer?
Just a thought since I haven't tired this yet.... What happens when you turn off phone audio(but leave media) for the car in the bluetooth settings on the phone?
