Bluetooth A2DP problem -- not playing through headset

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.

No voice on GPS while on Bluetooth

I have a strange situation here. My GPS will only read aloud when I am NOT connected to Bluetooth in my car. If I am connected to bluetooth while on the phone but not actually using the Bluetooth, using the handset to talk on the phone, the GPS voice comes through the earpiece on the phone. The GPS voice works fine when I'm not connected to Bluetooth in my car. Does anybody else have this problem? Any solutions? Thanks in advance!

Ditto!
I too had that problem. I recently was traveling for work and needed GPS in the rental car. I almost missed my exit because the nav voice wasn't working over the car's bluetooth connection. Calls worked fine but not the nav voice....

I have no idea what is causing it tho.

Under Bluetooth settings can you see if you are connected as phone and media or just phone? Every once in a while mine just connects as phone for some strange reason!

Both media and phone was checked off.....hmmmm....not sure why it doesn't work when connected to Bluetooth.

Ok, today I tried my phone with two different Bluetooth devices to make sure I got music and GPS out at the same time and I did so i know the S5 is capable of it. So check to make sure your devices are actually are connected as phone and media when paired next time just to make sure.I know my Motorola roadster2 sometimes only connects as phone even though it is set up as both, I usually have to reboot both the phone and and my roadster to get it to connect as both fir what ever reason. I hope that helps, if not I am at a loss!

I tested this the other day, and it works fine for me. I am using a Kenwood DNX8120 head unit, and it is connected with the S5 with both the headset and media bluetooth profiles. Note that the head unit needs to be on the bluetooth input for me to hear it since it is using the media profile for the GPS voice. If it is on another input (i.e. tuner, CD), you won't hear the phone's GPS.

Still nothing. I cleared my cars system memory and repaired the phone. The weird thing is that it was working when I got the phone a few weeks ago. It worked for a week, then all of a sudden stopped.

A tad bit late, but here nonetheless

I know this is an old thread, but I wonder if you were listening to bluetooth audio or not. If you weren't listening to bluetooth audio on your car radio, then you wouldn't hear the voice navigation prompts. Unfortunately I don't believe voice navigation works like the phone.
The phone will mute any audio currently playing and automatically switch to the phone.
The nav audio works through bluetooth audio only. It doesn't mute anything so unless you are listening to bluetooth audio you won't hear the prompts (they are there, but you aren't listening to the source where they come through).
I think the solution as stated was to turn off Bluetooth media profile so it only comes out of your phone and leave on bluetooth call audio profile so it comes through the car.

Bluetooth Google Navigation Voice Output Problem

Not sure if this has been discussed on XDA before - couldn't find it in search - but problem is this:
When I have BT activated on the N6P along with Google Maps Nav, the sound output (voice directions) is either:
a. When phone is set to BT stream music = sound command is partially cutoff at the beginning -​or
b. If the radio is on = No sound output is heard at all​
Google Nav is set to output sound via BT under its settings.
This also happened on my OnePlus One.
I thought I had read somewhere that this happen because of the BT format that Android sends to the car's audio system is incompatible.
Any thoughts?

Mine works fine in my car when playing Spotify and Maps at the same time. It lowers the volume and then speaks the command and raises the volume back up again. If it does the same with two devices, I'd guess it's related to the car not the phone.

Can Google Maps Directions be played thru Car speakers when listening to AM Radio?

I have a S7 Edge on Verizon. Phone connects fine to my Bluetooth in Honda Pilot, and google maps direction play through speakers when setting in car is set to Bluetooth. Is there a way to also get directions to play through car speakers when listening to AM/FM/Sirius radio when phone is paired with Bluetooth connection?

There used to be the option in the navigation settings to play through the phone speakers even when bluetooth connected, now I cant use fm radio and navigation without first disabling bluetooth.

No. However you can use a Radio app and stream through Bluetooth and still hear the feedback from Maps.

Well depending on a few things that you need on your phone if you don't already have them set up, then yes this is 100% possible and I do it on my s7 edge right now if I understand your question right. Just to clarify, are you asking if theres a way to get google maps to give you voice directions (through the car's speakers not the phone speaker) when its connected to your car's bluetooth but your listening to the car's AM/FM/Sirius which prohibits it? let me know and ill give you a potential solution if you want.

Yes - I'd appreciate it if you could give me a potential solution. Thanks.

Bluetooth stream to your car audio using Bluetooth input. Load up an AM/FM/SiriusXM App, play your desired channel, use Maps.
Not sure how you're supposed to trick your audio device into playing two different inputs simultaneously. Unless you find some kind of transmitter to can force a signal to override your radio somehow.

Google Maps Voice directions

Hi,
Coming from a Windows phone it was possible to listen to my music on my car stereo and have Near maps giving me directions.
It seems with Google Andriod I have to switch my car stereo to Bluetooth device to get voice turn by turn directions and no music.
Is this the case ? Or can I have both music and voice directions at the same time ?
cheers

On my us997 G6 I can have both. When the map gives voice guidance it pauses the music and then resumes when maps is quite.

Thanks thats good to know.
Is your setup using the car stereo for music or your phone ?
In my case the music was on in the car stereo.
cheers

As far as I know and experienced it only works with both coming from your phone to the car speakers.
Maybe depends on the car setup, but if I play music on the car with USB no audio from the phone via Bluetooth.

Aaah okay, thats the problem, and thats how Windows phone works, Car stereo music and voice navigation from the phone.
Also can Android voice text messages and can you reply to them ? Another thing I miss from Windows phone.

Hi!
I'm using Sony MEX-N5100BT bluetooth car radio. I can both listen to music and use navigation with voice directions without any problems. I'm using Spotify, when the music is playing and voice direction is played, music's volume is turned down a bit and then returns to normal value.
I have to use "Bluetooth audio" mode in the radio, then all of the Media sounds are streamed only on the radio (music, games, youtube, navigation), and all notifications and ringtones are played both on the phone from the loudspeaker and streamed to the radio at the same time.
What music player are you using?
Some of them have separate setting where when there is sound interruption from different app the music pauses for second instead of being played quieter a little bit. I had such option back in the days in PowerAMP.
About text messages and replying - I'm not 100% sure about the reading option, probably radio-dependent... AFAIR Sony's companion app for the radio has it but it works in English, not in Polish.
But I have some sort of Google Now integration in my radio, I can press the button on volume jog and Google Now launches, waiting for me to say the command, f.e. "SMS to ***"

My Car stereo is an Apline CDE-W235EBT thats what I play music on.
cheers

Maybe Windows phone uses the voice protocol for the voice directions on navigation, that's how it could interrupt your music you are playing on your car.
Android uses the media protocol for voice directions/music and the voice protocol for phone calls I think.
Is it such a big deal for you to play the music from your phone, so you would have the feature you want?

Thanks, krysden
It's more convenient to use the car stereo than the phone for music. I turn the key, engine starts, music starts and I'm on my way.
