Bluetooth no longer plays music through headphones, but calls still go through

Hey guys,
So okay, I am having an issue and have not been abe to solve it for a week now. Allow me to start...
I have the sony MDR-1RBT headphones. I've had them since last February and have used them without any problems. Connection, set up, and usage has always been a breeze. Until recently.
I started my day and connected my headphones like usual and it said they were connected. Cool. Went to play music and it played through my phone. Not sure why. Tried to make a call, audio went through bluetooth device. So they say they are connected and playing through the bluetooth device but is clearly is not.
Things I have tried to fix it:
power cycling phone and headphones
disconnecting and reconnecting bluetooth connection
gone into device settings and made sure media was checked for my bluetooth device
researched through the internet
followed what the person on this link suggested: http://forums.androidcentral.com/ge...r-playing-note-2-music-but-does-do-calls.html
The last step, when I tried it it connected! Yay! Then I turned the headphones and bluetooth off and went to turn em on again and it went back to not working. Tried the same method and it didnt work.
I am running on an LG G2 Rooted but not ROM'd. I know the issue is not with my headphones because I tried to connect the device to my Jawbone Jambox and it did not work on that either. I am not sure why it is not working.
I consider myself pretty tech-savvy and I am pretty upset that I haven't been able to figure it out. Let me know what you guys think.

When you go to your phone bluetooth setting with a list of paired devices, do you see 1RBT listed in there as "connected to phone and media audio"? This is very important because it sounds like it's only connected to phone but not media audio.
Do you have any other bt devices you paired up with your phone? Like wireless speaker or another set of headphones? Quite often if you have a few with power, there will be a race condition which one gets connected as media. But since you said music was playing through your phone speaker, I assume there is not conflict with another device. But nevertheless, just delete all your previously paired up devices in Bluetooth list to make sure there is no conflict. Remove 1RBT as well. After you remove everything, reboot the phone, and do a fresh pair up with 1RBT. See if that helps?
Also, try to pair up these headphones with another device, either phone or a tablet to make sure there is no issues with bluetooth radio on your phone. If you have access to another bluetooth device, try to pair it up with your phone to make sure everything is working as expected.
Let me know the results, and we will go from there.

I come from the philippines and i have the g3 also. my bluetooth connection was fine it connected to my car and headset but now it only receives calls but does not play music through my bluetooth headphones. when i press the play button on my headset it plays on the device itself. checked under bluetooth setting and call and media and audio was checked.
my device is rooted. i did a factory reset but the problem remains unfixed. please help. i have installed g3 tweaksbox but i dont see any mods that is related to music apps. i dont know what to do. i have considered unrooting and flashing stock rom.

I was having the same problem until I realized the volume on my jawbone itself was turned down.

Vectron's Suggestion Worked For My Bluetooth Headphones
I was heaving the same issue as the OP all morning. My Beats66 Bluetooth headphones were working just fine since I got my Alcatel Idol 4, with Android 6.0.1 (Marshmallow) phone through wireless provider CricKet, just 2 days ago. I primarily purchased the headphones for placing phone calls, just because most Bluetooth headsets I have purchased, and Android phones in general, are too low volume for my impaired hearing to make out. However, I do listen to music on them as well.
This morning as I am exiting a taxi, I hear music coming from my backpack. Somehow, something launched one of my music apps, probably the buttons and screen were activated while items in the backpack pressed against them. The settings said Media and Phone were connected to Beats66, and the phone did come through the headphones only, but the music would only play on the phone's external speakers.
I found this thread from a Google search, and Vector's post was helpful for me. I went to Bluetooth settings and highlighted Beats 66 headphones, then selected "Forget." I rebooted the phone, paired the headphones, and all my music apps play through the headphones now. Lets see how long it lasts right? Since this is a brand new out of the box phone, I did install numerous Apps, all of which want user authentication, permissions, and countless settings and permissions to interact with other Apps and phone hardware. Hopefully with everything getting set up the way I like my phone, (I'm particular about everything, or I just find the phone annoying rather than a tool), I won't make anymore changes that will alter the operating status of the headphones.
Thank you

I am experiencing the exact same issue on my LG G3 with my Skull Candy Wireless headphones. The headphones pair and phone audio works, but Pandora, Google Music and any other streaming audio app plays over the phone speaker. I noticed that I received a Carrier OTA software update on Jan 17, 2017 and am wondering if that is when it may have charged. The only way to resolve it so far has been to clear the BT cache. This is temporary fix as when you attempt to pair again it is back to only phone audio and no music audio.

My headset is not working with music until you turn off the phone audio just to play music. My phone is Lenovo A2010-a and my headset is Nia X2. Please help

Ever get this resolved? Still having this issue and so far only fix for me has been using Ti Backup to nuke all the bluetooth data, rebooting and then it'll connect fine. I also have Skullcandy BT headphones. Trying my car's BT too to no avail. Same problem. I think this is the same issue: https: //forum.xda-developers.com/lg-g3/help/bluetooth-calls-media-audio-t2837471/page4

I ended up buying an Amazon​ Moto G4 as it is slated to get Android 7.0. I honestly believe it had something to do with the last security update LG pushed out. Since the G3 is not updating I will attempt to root and rom at some point though recent search seem to show the LG G3 can't be rooted.

I rooted mine fine with Kingroot. Get Kingroot, root, install twrp and flash supersu then delete Kingroot. Worked for me at least.
As far as this BT bug with the G3 I don't have anything better than the data wipe workaround so far, so good luck with the Moto.

Thanks guys. I also had the same problem but i restarted my phone and my music is just playing. Yah!!!!!!!!!!

Bluetooth issues on official android Pie

Hi all...need some help with Bluetooth issues on my pixel 2 XL. I updated to the official Android pie today and noticed that my jbl Bluetooth earphones are having issues with calls. I cannot hear anything thing from the other side and the person on the other side can only hear some weird distortion. However I tried playing music on it and it works fine. Issue is only with calls. Anyone else facing this? I tried unpairing and pairing it again, restarted the phone, tried safe mode too but no luck.
Also I had sound echo issues with wired earphones (connected through dongle) on Oreo so I bought the jbl Bluetooth earphones and the echo was gone...and now after updating to Android pie my Bluetooth earphones don't work
Please help!

I have no issues wtih LG HBS730 BT headphones on calls or music with Pie. I've had four calls total, incoming and outgoing. I listened to music for about five hours too, no glitches.

I've had issues with the anker brand ones.

I have the same issue

Having issues connectingy to my car Bluetooth which has always worked before updating. Also experiencing WiFi drops.
Edit: went to stock Pie unrooted, and not as many wifi disconnects but my phone doesn't even see my car's Bluetooth connection . Fitbit connects just fine though. Weird..

Android Bluetooth is flakey as hell. Everyone gets a turn with incompatibility. P fixed my car with the first Dev preview. On O it was crud. There is a massive ongoing thread about it.

I had the same issue on my pixel XL on dp4 and dp5. Bluetooth worked fine for music but only crackled a little bit for phone calls. Both headsets and car were affected. Troubleshot it with Google rep and they told me my phone was broken. I also had multiple sensors stop working so auto brightness was broken and auto rotate was also broken (And a few other features like tap to wake screen). I ended up buying a pixel 2 xl and sending the other to Google as a trade in yesterday. Now I'm wondering if it wasn't just the software. I actually reset the phone and everything worked for a day or so before it failed again. I then exited the beta and everything worked on 8.1 Oreo for about a day before it all broke again. At that point I concluded it must be the phone. Hopefully the software didn't burn something up. I'm going to be ticked if this phone starts giving me trouble.

Are there any troubleshooting steps I can follow to see if solves the issue? Because it only happens on calls but music seems to be fine.

You can try rebooting in safe mode (long press the power off icon when you press the power button). I will restart with only minimal apps to see if it's being caused by a non Google app.

I tried this on my device but even in safe mode i faced the same issue

Ever since upgrading to PIE, I can no longer connect my my pioneer appradio head unit.
Phone works, but media Spotify or Pandora does not

Having the same issue, also, my "disable absolute volume" in developer settings doesn't work. I guess this is what to expect for early adopters.

I have had no issues with connectivity to my bluetooth headphones or to my car's bluetooth
However I have noticed that twice when I had phone call before entering the car and I connect to the car's bluetooth and the call is transferred to the car's audio, I get disconnected for a couple of seconds (after initially connecting correctly) and then it automatically reconnects and call continues normally ..

Stock Pixel XL: All bluetooth devices worked for all purposes on Oreo. After updating to Pie none of my bluetooth headsets will connect for phone calls. Bluetooth music broadcasting to speakers is unaffected. I'm going to call them about it tomorrow.

Are you having any other issues. My original pixel XL had the same issue show up on the beta but it also affected some of my other sensors as noted in previous post. I now have a pixel 2 xl with no issues whatsoever.

Well, they seem to think that the problem is an app from the play store that doesn't play nice with Pie. Frustratingly, the problem corrects itself sometimes (but not all the time) after a reboot. They had me reboot into safe mode and this time it worked. After 20 minutes our support call was over. 30 minutes later one of my three headsets (with the oldest bluetooth version) didn't work, but two of the three did.
The tech (Jen, who was super nice but sounded like she was overseas and had to repeat herself a few times for clarity) said they only have 2 support options for this issue: 1) boot into safe mode and blame one of the apps from the play store or 2) FACTORY RESET THE PHONE! Once I explained that the phone was my google authenticator she suggested that to further troubleshoot I should turn off two factor for my google account (Ummm, no thanks. And that is why you should always PRINT OUT the QR code and put it in a fire-proof box in case you need to recover it)
I'll post back if it breaks again, but right now at least I can live with it.

Only "issue" for me is my wife's ILX doesn't seem to update the music information anymore. With the betas it did for a fee songs then seemed to stop. Now it's nothing at all but will double check today since I only drive it on occasion. Other than that, playback on our cars, Bluetooth speakers and headphones has been just fine. Love that it remembers the volume set per each device. No super low or super loud volumes on the start of playback.

I also have Bluetooth issues with Pie when connecting to my car (2017 Audi A4 with MMI+) I never use Android Auto by the way:
- Music playback is flaky: I have to start Play Music before connecting to the car, otherwise it cannot stream anything. Sometimes even this doesn't work and I have to repair again. This sucks, you always have to spend some time to check if everything works!
- My Radar trap warning app blitzer.de only works when streaming Audio from the phone to the car, even though I set Audio to HFP. With Oreo, the app started a phone call, it looked exactly like an incoming call. Now it only adds the warning to the phone's Audio Stream, so when listening to radio or streaming from a HDD I get no warnings.
- Phone calls work flawlessly, though

Try removing or 'forgetting' paired device and add it back again. It worked with my AirPods.

Headphone Sensitivity Problem

Over the past several days I have encountered a serious problem whenever I try to use headphones with my Mi 6. When I have a headphone plugged into the audio USB dongle and attempt to play music, at the slightest vibration, tracks will start and stop playing, tracks will change, the volume will shift, and the microphone will activate. This has made it almost impossible to listen to music with the phone anymore. I have tested this with two headsets, which both cause the effect, though it does not happen if I do not have a headset plugged in. Because I have had this phone since soon after it was released, my guess is this problem was caused by a recent MIUI (I'm on 10 8.10.11 Beta) update. It kept occurring even after I installed Blackplayer and tried using that instead.

It sounds more like a hardware problem to me, dirty or loose connections

I tried cleaning everything as best as I could, but to no avail. Does anyone else have any experience with this problem, or is there a way I could disable the phone from accepting input from the USB port so that my headphones will be usable?

Bluetooth no audio in Bmw 323i 2010

guys
pixel 3 xl is not playing well with my BMW 323i 2010 bluetooth call system.
When i get a call the ringtone comes through the car speakers. Then when i accept the call there is no more audio through the car audio system.
i tried unpair and reparing and same issue.
my original pixel xl works fine.
any idea? any1 having similar issue?

I have a 2013 328i, and this is the first phone I've had since the Nexus 6 that actually works well with it for music. I always had problems with the Bluetooth freezing.
Sent from my Pixel 3 XL using Tapatalk

sometimes telling the assistant to play music will get it to play nice if it is still paired just not sending audio. but for phone calls, thats weird

Did some troubleshooting today.
So after connecting the call if I manually select phone on the pixel3 and then switch to car audio Bluetooth then it starts working.
But it doesnt start automatically when the call connects.
I will log it with Google and hope for a fix.
Thanks guys.

Try resetting the cache for the Bluetooth app in the app manager in settings (You have to tun on system apps to see it)

2013 BMW 328i, never had an issue with any other phone, seems at random call audio will stop working over Bluetooth in the car and the only remedy is to reboot the phone. Have tried everything with no solution.

yep, my issue still not fixed and making me crazy.
1 thing i am gonna try today is that disconnecting p3xl from my samsung gear s3 and see how it works while only connected to bmw's audio. if that does not work then i will send this phone back.
it is insane how many software issue this phone has.

Argh, same thing with my 2011 128i. NEVER had a single problem with my Pixel 1 XL, got the 3 XL a few days ago. Today I need to make a call in the car, pair the phone and... no audio. In fact I think it was still playing music, even though it showed "Connected". I have the "Professional" audio system; ie: the simple one. Not with the big display etc, iDrive I think it is.
Could you let me know the bug ID you logged and I'll star it and participate in it with logs etc as they request them? I don't make a lot of calls in the car but I often drive into work listening to conference calls so this is seriously annoying.
My two bluetooth headsets work fine, so it doesn't appear to be a overall issue with bluetooth headset audio etc. I might try it in my wifes car just to see if it works there, for more datapoints too.
Very, very odd... I read a suggestion to boot into safe mode and connect the phone to the car and that worked, everything is fine now. What's stranger, to me anyway, is that it continues to work fine! But as odd as it sounds, this is something to try.

Bluetooth Headphones Issue

I have an issue with a new pair of bluetooth headphones i have just purchased. Specifically media playback sound quality. It is utterly woeful, with distortion, hiss, and cackles/pops continually over any media player or videos. Sound quality on calls is fine. I know that the headphones work, as i have used them on other devices and they function fine. My S9 is currently up to date.
I initially though that it was something to do with volume limiter as the weird thing is occasionally when they immediately connect and i play some music they work fine, then the quality drops as soon as the limiter notice pops up. I have checked though and the limiter is actually turned off. Turning it back on doesn't solve the issue either. I've gone so far as to wipe the whole cache partition and nuke all the caches, but that hasn't helped either.
Is there a known issue that I am unaware of ? Hopefully with a resolution, or other obvious steps i could try that people could recommend, as I am out of ideas now.

i flip back and forth between a few different BT headsets and never have this issue and have also used the same headsets on several devices in my bag-o-tricks. The phone does use a DAC for music where its pretty raw for the phone convo, which could explain why calls are ok, but music isnt. Is this your only pair of BT headphones? Do you know anyone who will help you test them on another phone?

I have experimented a bit more, and think that this is a codec issue. If I enable the developer menu, and switch to another codec (not the SDC if defaults to) them restart the headset they work fine. Problem is that it always defaults back to SDC whenever the headphones are disconnected for a period of time. I can't see how to force the use of another codec, both AAC and LDAC for example work absolutely fine with the headset. Though this is quite a long process just to get the headphones to work each and every time i want to use them.

I last updated 02nd August 2019. I have just checked again, and apparently running the latest version available OTA.
I couldn't tell you when the bluetooth sound issue started, as this is the first time in a long time i have connected any bluetooth headphones to my phone. I think previously connected the other headphones i have yet to check again, but am not certain.

gotcha. i also understand youre probably at work like many of us poor schmucks such as myself, which would make it kinda hard to test things out right this moment. But do any of your coworkers have a BT speaker you can connect to to try to replicate the issue there as well? Im mainly trying to eliminate variables at this point. You might try flashing the most current Odin files with the "HOME_CSC" as to not erase your user data. Itll over-write the code for the OS and so forth and nuke any software issues that might be causing this

I've now tested another set of bluetooth headphones and they work absolutely fine, they default into the aptX codec. Is that determined by what the device primarily works with ?

yes, the codec is changed by the DAC within the phone to be the best suited to whatever device its connecting to. What kind of headphones are you using that get the garbage sound? I have a pair of Tozo T10's, which are the off-brand individual ear buds from amazon for $50 and they sound very good. I also have a pair of maxsonic bluetooth buds which cost $17 that are connected to each other by a wire and they sound equally as good.
