[Q] Bluetooth Connects but sometimes no Media Sound - Nexus 4 Q&A, Help & Troubleshooting

I have a Nexus 4, still running 4.2.1.
I use bluetooth headphones with it which generally work. However, sometime they connect and media sound still comes out the phone speaker,
Disconnecting and reconnecting doesn't help. The awkward trick I've learned is to run the Vonage phone app, and make a phone call, which some how turns the media sound on in the headphone.
There has to be a better workaround than that.
I know there were some bluetooth fixes in 4.2.2, but I don't want to upgrade until I've tested LTE which rumor says is coming next month in Atlanta.

No replies? I can't be the only one seeing this.
I can be a little more definite. It seems that on the first bluetooth connect from an ad2p device after a reboot, media sound still goes to the internal speaker. As I mentioned above I happened on a terrible workaround. If I invoke the vonage app and place a call with it suddenly the bluetooth device takes over the media sound.
It's painful to have to make a call just to kick the bluetooth headphone into media mode.

I don't know if it is the same issue, but my ad2p cuts out sometimes and won't work until a reboot. (It still shows up as working, and sound stops coming from the phone, but...) On 4.2.2 here.
I'll have to give your placing a call trick a try.

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.

Why aren't bluetooth microphones supported?

I just assumed that I could use any bluetooth microphone for voip, voice recording etc. I currently do not have any bluetooth device but I tried 3 at a friends and they all paired for sound, but failed to work in using a voice recording app or a voip app. In a voip app the sound went strange (long sounds on the dial tone buttons) and then the sound resumed coming out of the tablet even though the headset device was showing as connected. Only a reboot solved this.
So I assume the bluetooth stack doesn't support recording, but why not? Isn't this a basic thing at this point? If I connect a bluetooth headset with mic that should be my input and output on sound for the time it is connected.
Or has anyone had success with a certain bluetooth model for recording?
No one can provide info on this? Is this the norm for tablets? I would assume even some ancient gingerbread phone would work with bluetooth headset/mic.
Does cyanogen team ever modify the kernel to include more functionality such as this?
I'd check other bluetooth threads around this section, but I've heard several people who've used bluetooth headsets with Nexus tablets. It may be a setting issue (particularly the device setting under bluetooth and the app settings concerning headsets).

Same here, Plantronics bluetooth headset works perfectly for voip calls using Talkatone.
Thanks for the info. I don't have the model names off-hand but I'll ask my friend what they were. I wasn't aware that once a bluetooth device was paried that there were any additional options. I was under the impression that it was simply pair and use. With the case of a headset/mic I assumed it was inherited as your sound output/input for all apps while paired. The voip I tried is csipsimple and a voice recording app. I'm glad to at least some models work but I hope it isn't hit and miss and you have to be selective of what bluetooth device you use but rather something I was doing.
I didn't expect there to be any settings as well because even with no bluetooth recording device paired, I don't see anywhere in the settings recording recording (like mic volume).
Can't get mine to work. Single ear set I don't even get sound. Just dead air all around. The Southwing SA505 stereo gets sound fine but no mic function and on Groove ip no sound or mic on single ear or stereo. I even checked the settings making sure bluetooth was selected.
I'm from Canada so I can't try talkatone as I can't get google voice. I now purchased a btheadset. It pairs fine and I hear audio in all apps but I haven't found one app yet that works with the bluetooth mic. I wanted a voip sip app. I've pretty much tried all the free ones and other users have posted comments of bluetooth issues as well. There are a couple of paid sip apps that claim to support bluetooth, but I don't want to buy them to only find they don't.
So yes, android supports bluetooth mics, my thread title is inaccurate, but it seems the vast majority of recording apps do not have proper bluetooth support. Can someone name any app besides talkatone, even a voice recorder that works with bluetooth so I can just test it?
I'm actually surprised it's this bad. Bluetooth audio isn't that cutting edge. It should pair and now act as your soundcard so to speak. I initially thought to blame the OS because I thought any app that requests to play a sound or record a sound, would be re-directed by the OS to now use the bluetooth device.
I'm pretty sure it works exactly like this on windows. Or for example, I have a usb headset on my pc. It shows up as a soundcard. I make it the default and every app now uses that. No developer had to code to use a usb headset/mic, it just works.
Again a little disappointed that it's been a little trying just to get a bluetooth headset to function properly. I tried 3 at my friends that all pair fine and work flawlessly on his playbook in all his apps, and now I bought 1 so it's hard to say all of these bluetooth headsets have quirks and don't work properly with android.
Still trying to get this working. It pairs fine, and shows in the bluetooth details as being connected with phone audio and media audio.
It's a Aluratek ABH01F which I've read great things about. It supports a2dp. I'm not too familiar with bluetooth and microphones so I'm not sure if there is anything else to check for android to support a bluetooth microphone.
I don't know why I didn't think of it before but I tried google's voice search and it doesn't work either. I can hear the audio fine, just no mic.
Can anyone confirm if google's voice search works with their bluetooth mic? You probably have to walk out of the room to verify it's not the units mic that is picking it up obviously.
I'm not convinced bluethooth mics work at all on the nexus 7. I could chalk it up to my headset just doesn't place nice with the nexus 7 but again I tried 3 bluetooth devices at my friends. I found this post on another site:
Well, I got around to testing a bluetooth headset. single earpiece, Avantalk AH28. Not the best, but it works fine with a phone. Paired with the tablet fine. I dialed on groove ip - dial tones came from the tablet, the ringing transferred to the earpiece, when phone was answered there was no sound transmission at all- not from the bluetooth earpiece, or from the tablet. Just dead air. Tried it twice.
2nd test- google music played from tablet- not into the earpiece.
I have a stereo bluetooth headset with mic that I can test with but will have to charge that one up first. Will get back to you.
************************************************** ****
Got to my stereo Southwing SA505 bluetooth test. It worked to play music from tablet beautifully. Did not work with groove IP- went in and made sure settings were set for bluetooth- Mic did not work.

Again, I hear audio fine via bluetooth, so I wonder if some of you were thinking the bluetooth mic was working but it was actually the unit's mic.
This app called tapemachine specifically states it has bluetooth support. It fails for me when I change it to bluetooth in the settings, can someone else try it?
https://play.google.com/store/apps/details?id=com.samalyse.free.tapemachine&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5zYW1hbHlzZS5mcmVlLnRhcGVtYWNoaW5lIl0.
So I'm starting to think my thread title is correct. If I am, I'm hoping there is a way to hack some file changing the available audio profiles. I've read others doing something similar with different devices when the manufacturer disable those audio profiles. I would find it doubtful that google/asus would do this though.
Anyway, if anyone can try that app, or confirm that say grooveip is using the bluetooth mic and not the device. An easy test is tap on the unit mic while recording and see if you or the person you are talking to hears that.
No one? I know a couple of you said it worked, but are you sure grooveip is actually recording via the mic? I can hear phone calls using various sip apps with bluetooth, but I know the mic isn't recording. One of the headsets my friend has is a Motorola MOTOROKR S9 Stereo Bluetooth Headphones. Link here: http://www.amazon.com/Motorola-S9-Bluetooth-Headphones-Packaging/dp/B0017KTOJK.
I've only tried stereo headsets, so maybe that is the issue. The Motorola HS850 is a single ear piece, I'm not sure what plantronics set you have.
I'd really appreciate if someone else can verify if bluetooth is working. If bluetooth recording in fact works with the nexus 7, I must be really unlucky with 4 headsets that don't, which I find highly unlikely or nexus 7 has poor bluetooth support. The only thing left is my bluetooth hardware is broken which I find even more unlikely. Aradreamer, you say you've seen several posts saying bluetooth works, but I haven't found one post explicitly stating bluetooth recording works. I found more post on other forums clearly stating it doesn't work.

odd odd ...
first off i have the Nexus 7 16g with it rooted.
heres what i did first i bought the samsung HM1200 didnt thoroughly test that 1 because i figured it just wouldnt work with the device ( or was broken ) once i started to get all this screeching out of it... i heard sound momentarily then all it did was the screeching at different levels. returned it yesterday. then i added a couple more bucks ( about $27 total ) and got the plantronics M20 took it home and crossed my fingers. got it all it paired up and what not and ended up with the same condition except now the mic is working perfectly. i tested this thoroughly now over and over inside and outside and also away from the N7 to be sure the mic is working. this is great BUT i cannot hear any sound at all coming in to the N7 except the same screeching at constantly varying levels. this is with both grooveip and talkatone. i also tried uninstalling beats audio and rebooting but i read somewhere this wont change the drivers back to the originals and i still have the same condition. i just got the N7 about 3 weeks ago and the store where i bought it has a price guarantee so i am today planning to return it and get the N7 again but this time the 32g version. ( they got 2 left so i will be going ASAP. ) so almost all the work i put into setting this thing up is about to be wasted. still i am going to do it anyways. to me its just the point of getting the best i can with my available budget/resources and i can easily see this thing be full and kicking myself in the butt for not doing it. this time around i will test all of what i mentioned here BEFORE i root it. in fact i will only install the necessary apps ( grooveip/talkatone etc.. ) during testing. its a real pain in the butt but it is a MUST i have this thing working as a phone with BT asap. thanks for the input and i will report back later.
update: actually in a more quiet room i was able to hear myself on the BT headset but very very low and in the background behind the screeching. still will report back later with the new unit.
For some reason the Bluetooth headset profile on the n7 is totally broken. I tried MANY headsets and none of them work. It is either the drivers, the hardware or the kernel. I hope it fixable in the 3g version.
Sent from my Nexus 7 using xda premium
yep i am sitting here now with the 32g N7 and the first thing i did was try the BT unrooted and its the exact same thing screeching like mad can hear myself on the mic perfect from the other phone and can hear the other phone low in the background of the screeching on the N7 ugh
i have a temporary solution that should work till its sorted.... i need a new headset for my computer anyways so ill just make sure to grab one that is USB then when my OTG cable arrives i am pretty sure that should work. it will be corded but at least i can use the phone somewhat normally for free. ill let you know. now im off to rebuild the whole thing back to where i had it in the 16.

Bummer. Hopefully they fix it with 4.2 or with the 3G version.
It also seems that if you try to toggle speakerphone / BT headset in various voip apps the tablet will crash and restart.
I tried with GrooveIP, Talkatone and the build in phone app (After changing the framework-res.apk file).
I also noticed i had better luck getting the BT headset to fully (and randomly) work when doing outgoing calls. It never worked on incoming calls.
Any progress on this?
I've noticed the same problem and just returned a BT headset due to the problems in GrooveIP & Talkatone
As a side note I was able to get the BT headset to work as a MIC with the google voice commands by using the following..
- Soundabout
- Under BT settings set it to force mono BT mic
- Set audio to wired headset
Just as ref, I'm using my N7 in my car, so my setup may be a bit different.
But this worked, I was able to tell my N7 commands and it would read out the response over my car speakers.
Anyone had success with a USB mic? Curious if that will work.
I'm very interested in this thread too.
I have a 32GB nexus 7, rooted and unlocked. I have a Platronics M100 bluetooth earpiece. My goal is to be able to dictate to Evernote through the BT earpiece. It is pairing and under the connect settings it is showing up as "phone audio". But when I speak into it nothing is happening in Evernote. I also do not get media audio through the earpiece.
My Sony xperia Z accepts audio from bluetooth microphones, but only during a phone call.
When the call is terminated the paired bluetooth mic becomes inactive and the phones built in microphone takes over. I have tried many apps but none will accept audio from a BT mic.
I have tried a number of headsets and speakerphones and they all behave in the same way. Sound is not a problem as the BT speaker simply replaces the phones internal one when paired.
The xperia Z has a setting which claims to: " record audio through bluetooth headset if available", but this setting does nothing. I keep retrying the setting at every android update, to no avail. Currently at 4.2.2.
When I plug in a wired headset, the speaker and mic simply replace the ones in the phone. Why doesn't bluetooth behave in the same way?
This issue has been raised in many forums, in relation to many android devices, but never answered.

[Q] CM10 a2dp issue

First a big thank you to dev(s) for their awesome work.
Been using CM10 beta as daily driver on an unlocked aussie RAZR m however there is another possible small bug: when you have a Bluetooth headset connected, phone audio goes to handset but media audio goes to the external speaker no matter what you do.
Anyone else have this?
Sorry couldn't post this in the cm10 thread .
Sometimes this happens to me, even before I rooted, even on my droid 2 global, sometimes a reboot of the phone does it for me or removing the bluetooth profile from the phone then connect it back up does the trick. I have a Insignia NS-BTHDP bluetooth headphones.
I tried this morning to connect my motorcycle helmets BT. Same thing, paired right up, but audio only went out phones speaker

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.

[Q] i9100 no Bluetooth audio

Phone Samsung Galaxy S II
I am having a problem with no audio being routed to my Bluetooth in vehicle. This is a critical bug for me due to where I live having one of the strictest distracted driving laws.
After turning on the device no audio is working during calls. Mic and speaker since neither person hears anything.
Media audio doesn't work either. But I have found a non permanent fix for that.
If I connect to Bluetooth and start music it is silent but if I go into the Bluetooth settings and choose the preferences for that specific device and toggle the "media audio profile" off then on and restart the music it will work fine until I lose the connection. I have to repeat every power on.
The same type of fix doesn't work for call audio though.
Edit: Just noticed if I leave the phone audio profile turned off that media audio works fine all the time.
I too second what shadowofdarkness has mentioned in the post before. I have an "HBS 700" headset. When both profiles phone/media are on, and you hit the volume rocker the bluetooth audio is disabled. You disable both and enable media audio alone and it works fine sometimes. Else unpairing and pairing back and enabling only media audio makes it work without a hitch. Enabling phone audio at anytime brings us back to this issue.
