**Resolved** Vehicle Bluetooth music and navigation issue - ONE Q&A, Help & Troubleshooting

****Update : I ended up doing a fresh COS 13.1.2 install and it resolved the problem. Still no idea what caused it in the first place, but it seems to be a software issue rather than a hardware issue.*****
I have a stock OPO on the latest 13.1.2 Cyanogen build and OTA updates. I use it to stream music via Bluetooth from Google Play in my Ford F150 with Microsoft Sync. I do a lot of deliveries in the truck, so I use Google Maps/Navigation quite a bit, playing the navigation directions over the truck stereo speakers. The two have always worked well together, with the music dropping to a low volume level when the voice from Maps announces the next navigation point. Then the music goes back to the original volume.
About a month or so ago, I noticed that I wasn’t hearing the the driving directions anymore. The streaming music would drop the volume, but there was no voice announcement playing over it. And then it would go back to normal music volume. It is like it is trying to play the voice, but I’m hearing nothing.
The Ford stereo has a pause button that will stop the streaming music from playing, and when I press it I can then hear the driving directions again. But press the button again to start the music, and the voice is gone.
If I play the music and navigation over the phone’s speakers it works fine. If I get a phone call in the car I hear the navigation voice and my phone conversation over the car’s speakers at the same time.
I’ve tried Waze instead of Google Maps and it does the same thing. I’ve re-installed all the suspect apps to no avail.
I have no idea if there was a firmware/software/app update that happened around the time this behavior started. I already checked the settings in Google Maps to play voice over Bluetooth and during phone calls. Anyone have any insights? Thanks!

[Q] Bluetooth audio streaming problem

I've been having an issue with the media audio streaming to Bluetooth on the Blaze, which I did not have on my previous phone (Optimus). I pair with a Soundfly View in my car, and use the app BeyondPod to listed to podcasts. On a "fresh" Blaze, the audio will begin to play/stream for a split second, and then stop (though the podcast will continue to "play" or advance on the phone). I can occasionally get it to do it again by clicking play, but never for more than that split second.
Through experimenting, I noticed that phone audio seems to be fine, as well as audio on the Music player. What I've found, consistently, when this happens, if I start the Music player, start playing some audio then pause it, then go back to BeyondPod, it streams fine. At least for a time, though I've yet to figure out exactly what "resets" this workaround. But when I'm unable to play, I have to redo this Music player trick to play the podcasts.
Any clue what is going on here, and any permanent fix?
Bluetooth streaming... I have been doing this for a few years using a slightly different method that I'll share here in hopes it might help. I know this is kinda unrelated to your app, but this might be a fix.
Connect any bluetooth headset (I use my PS3 headset)
Download an app called BTmono (its free and a very simple interface, on/off)
Press the on button
Now any sound you would of heard out of your phone speaker you hear on your headset. This lets you listen to music, audio books, videos, or whatever on your headset. When you are tired of it, make sure to press the off button on BTmono to go back to normal. Hopefully this will help or at least provide a temp fix for now. My boss just thinks I like to wear mine all the time, he has no clue I am jamming dubstep and listening to audio books all night
Well, even should that work, it's really the same solution...using another app to force the streaming which should be happening automatically if you're connected with the right BT profile.
I did forget to mention that I do use A2DP volume, which launches an app (BeyondPod) and adjusts the volume when BT is connected. I also used it on my old phone, so I doubt it's related, but...
Nobody else has any problems with Bluetooth from other apps? It's just me???

All Media Except Pandora Play Through Bluetooth

Running Codename Android
I set up my phone to play through a Bluetooth stereo dock and at first BeyondPod wasn't playing through it but Google Play music was. BeyondPod Started playing through the speakerphone instead. When I realized Play Music was working I opened up Pandora and it also played through the Bluetooth.... until the first song ended and it switched over to the speaker phone. Oddly enough, BeyondPod then started playing through bluetooth. I rebooted the phone and now Pandora is permanently playing through speaker phone only. I downloaded and used BT mono, which caused Pandora to play through Bluetooth with a 15 second delay, but when I shut it off it played through Bluetooth perfectly! I rebooted my phone and it is back to speaker phone only. Now BT mono does not affect it at all.
Summary of what I have tried:
Two separate Bluetooth devices, same behavior
BT mono app, worked at first (crappily) but now has no effect.
Multiple reboots, cleared data and reinstalled Pandora, no effect.
Unchecked and recheck BT setting in Pandora, no effect.
The Bluetooth devices are set to "media" in the bluetooth setting, and one of them was set to "media" and "Phone"
Is this a ROM issue? I love this rom... Any other ideas? I don't think it is a problem with the bluetooth devices considering every other app works fine.
Ok so to add to the mystery, I just tried Double Twist, and it did exactly what pandora did. It played the first song through Bluetooth, and when it cycled to the next track it went to speaker phone. Now I can't get Double Twist back to Bluetooth.
IF anyone is following this, I have found that if I enable BT Mono, the sound stops playing from the speaker, and when I disable BT mono it start playing through Bluetooth.
So just a toggle on and off and it randomly works, sometimes it does nothing though. It's incredibly inconsistent.
Could this be a kernel issue?
Appears to be a general CM10 issue. Sorry.
Not sure what the issue is but I have a Samsung Galaxy Nexus with the same issues. I'm trying to find a fix but nobody knows what is going on. I saw on other forums someone referencing the AVRCP version with new builds. Not sure if this is it or not. But I have a 2011 Toyota Camry it will not pair with for Pandora, YouTube, etc... Google Music works but that's it. And I can replicate your issue. If music is playing, I can hear notifications but if it isn't I don't hear anything.
Not sure if this will work for you but it worked for my HTC One and 2011 Sienna:
Launch pandora
Launch Google Play Music
Under Manage apps, select Google Play Music and stop it.
Sometimes Pandora starts streaming at this point.
If not, select Pandora from Running and stop everything under it.
Restart Pandora and it should stream now.

Bluetooth issues

As the title states, I've been having BT issues since day one with this phone. I have the phone paired to my 2012 Toyota Camry, but the car interface simply shows 'STREAMING AUDIO' as soon as the phone is connected via BT. problem with that is that the interface only shows streaming audio when something is actually being played. That isn't the case with the 1+1. I am not playing any audio, or making any calls, yet the car interface will show 'STREAMING AUDIO', with no sound being output whatsoever.
Intermittently, however, the phone will start Google Play Music as soon as BT connectivity is established, and play an Unknown Track, even though I have no music or audio files on the phone. This doesn't happen all the time, however. I've tried closing all Google Play processes to see if that will help, but I've had no luck.
I am stumped. Any help would be greatly appreciated. I'm guessing its an OS problem.
Bumping this thread. Still looking for a solution to this problem.
Bump, with an update.
I finally got around to purchasing some music thru Google Play, and it seems as if the Bluetooth will stream audio only played thru Google Play Music. YouTube et al still do not work, however.
The weird part here is that I've been using the app "YouListen", which allows me to play YouTube audio while in the background. I noticed that whenever I am playing simultaneously through YouListen and Google Play Music, I will get audio from both streams. Shutting off Google Play Music will shut all audio off.
I read around, and there seems to be an issue with specific models in which Google Play Music gets first dibs on streaming audio, and so there is an option in Google Play Music to shut this off in order to play audio through other apps. However, the 1+1 doesn't have such an option, so I'm not sure the problem lies there.
Again, any help would be appreciated.

[SOLVED]google voice and music problem on headphones

Hi guys! I've recently noticed that when my headphones are plugged in and when I'm listening to music on my phone google voice randomly activates and stops my music from playing. Sometimes my music pauses or skips tracks randomly without activating google voice. Even my phone started dialing last called contact while my headphones were plugged in and I didn't even touch anything nor I was listening to music. It is very annoying to have google voice activated out of nowhere or to have your phone randomly skips or play/pauses music while headphones are plugged in. That problem is not just appearing while I listen to music but it can appear when I watch videos on youtube. When I take out headphones my phone works great but when I put headphones back in, my music plays randomly or google voice search activates.
First I thought it was a rom bug and I flashed another rom but problem was still there. I even tried different headphones and it didn't help. Google voice was still activating and music was played and paused without me touching anything.
Can anyone help me to solve this problem? It's very annoying.
EDIT: I've found solution in this thread.

Stop automatic bluetooth audio playback upon connect

I have tried 3 different phones including my latest an LG G3. Whenever the phones connect to my Subaru radio, and the audio source is selected as bluetooth, the phone will automatically open the last audio app I had running (Podcast Addict, MixZing, etc.) and start playing where it left off. I have looked all over for options and so far only found one to "not resume playback after phone call." While this prevents any audio playing when I hang up, I don't want audio to start playing just because my phone connected to the car's bluetooth either.
How do I disable this?! Hoping I can do it form the phone end. Saw no way to do it from the car's radio.
No one?
N7player has a setting called "Resume after Plugin" under Headset controls. I think that's what you're looking for. (Since it sees a bluetooth radio as a headset).
I think i have this problem too.
I have BBC iPlayer app, and I tend to use it to listen to live radio, over wi-fi when I wake up in the morning. Then I close the app and usually swipe it away.
When I drive I often use Google Maps or Sygic app as a Sat Nav, and connect the phone to my car stereo via Bluetooth so the audio is routed through the car stereo. Often I also listen to music from Google Music (downloaded only), and that works well, with the music being muted automatically for voice instructions. But when I don't want to listen to music, and just have the voice through the radio it keeps starting up BBC iPlayer Radio which then uses up my data allowance. If I wanted to listen to the radio I would use the car radio. Having read this thread I guess it is starting BBC iPlayer because it is the last audio app that was being used.
I noticed today that even if I stop the app, and swipe it away, if RDS TA (FM Traffic Announcements) break into the audio, when they end or I cancel them, the BBC iPlayer app starts up again.
I don't want to be having to keep stopping it while I am driving. I hoped there was some way of stopping it.
