[Q] G2/Acura Bluetooth audio mess

I recently discovered what a treat it is to play audiobooks while I drive.
And allegedly, my G2 and Acura TL Bluetooth Audio (2011 Acura TL w/ Tech package) makes that a snap, right?
Well, here's my experience.
1. I turn on my Android phone's Bluetooth (T-Mobile G2) and get in the car. The car immediately recognizes the phone. Great!
2. As soon as I switch the car's radio/audio button over to Bluetooth audio, my phone instantly pulls up an MP3 player and begins playing a song.
3. But I don't want a song! In fact, there seems to be nothing I can do to stop my Acura from ordering my Android to play something every single time I switch the radio to Bluetooth audio. Or is the phone itself that wants to automatically play something? Who knows. It's annoying. I thought maybe the problem was an app, because it was always DoubleTwist that would automatically start playing. So I deleted DoubleTwist. Now it's WinAmp that starts playing. So it must be something about the phone interacting with the car. For whatever reason, I now have to dial the Acura Bluetooth menu over to Pause/Resume to stop it.
4. Finally--after all that--I can pull up my audiobook player and start to listen via Bluetooth audio. Bliss.
5. Oops, there's my phone ringing, which my Acura Bluetooth phone function quickly answers. It's my wife.
Wife: "Hi, I just wanted to see if you're driving your car."
Me: "Why, yes. Yes, I am driving my car. Thanks so much for asking."
Wife: "OK, goodbye!"
Me: "Goodbye. Thanks so much for calling."
6. When the phone hangs up, ALL Bluetooth audio ceases. I think the connection remains, because any player app I have will show the seconds ticking off if you ask it play something, but you can't hear anything, neither on the phone speaker nor on the car audio. It's as if the phone is transmitting it to the car but the car has its Bluetooth audio turned completely down? Who knows? But it's a bummer.
7. No button-pushing on the car seems to fix things, so I turn the Bluetooth radio on my phone off, then on.
8. Now, we're all reset. Whoops! There's that annoying song again. Got to turn that off. Then back to the audiobook player. Then back to the book.
9. Five more minutes of bliss until the next call.
10. I dunno. Shouldn't this be easier? Hopefully, I've pulled off the road several times while all this was going on. If I try to deal with it while I'm driving I'm certain to wrap my car around a telephone pole, which is embarrasing no matter who you are.
I'll probably have to cross-post this to both the Acura genius's board and the G2 genius's board since I'm not sure where the issue lies. Let me know if you have any clues.
Thank you!

Okay! I got a little schooled by the Acura guys. I really shouldn't consider it a bug that something starts playing on my phone when I click the car radio dial to Bluetooth Audio. That would be like expecting the FM receiver to stay silent until I've selected a channel. As soon as I select Bluetooth Audio, it sends out the Bluetooth Play command and away my G2 goes. Not a bug. Feature. Got it.
Here's the part where I need Android geniuses to weigh in.
I use the Ambling Bookplayer app. For some reason, even if Ambling is already playing when I select Bluetooth Audio on my radio, my phone will still launch a standard media player (such as DoubleTwist or WinAmp) and begin playing a music .MP3.
At that point then, I have both the audiobook .MP3 and the music .MP3 playing through my car's Bluetooth Audio.
What is behind that behavior?
The only thing I can think of that might be a clue is I've noticed that the same media player always launches despite the fact that I have several on my phone.
For example, it was always DoubleTwist. I deleted that app while troubleshooting this problem and now it's always WinAmp. I wonder if there's some kind of hierarchy in determining which player responds to the car's "Bluetooth Play" command? If I had a music .MP3 playing on the stock music player, would the car still launch WinAmp?
And if there's a way to determine who goes first, can I figure out how to make it the Ambling player?
Anyone who has some insight into the relationship between Bluetooth and Android or G2 media players, I'd certainly appreciate some input.
Thank you!

Closer...
So it occurred to me that since my car is always asking for the same player, there may be a "default player" setting somewhere I can change. Perhaps it's the "default .MP3 player"? I discover that the audiobook player I've been using isn't even listed in the menu of available media apps that appears when you click an .MP3 file.
So I downloaded about every audiobook player app and it turns only ONE of them does (MortPlayer Audiobook).
So I click the box to make this the default player whenever an .MP3 file is selected. Maybe that'll work.
I go back to the car and select Bluetooth Audio. Nuts. WinAmp again.
So that suggest to me that the default player setting I'm looking for is a Bluetooth default media player? Is that the answer I've been looking for? Is there such a setting? If so, how do I change that?

I've worked through most of the problems above, but I'm bumping this because of one unresolved question:
Doesn't anyone here know exactly how the G2 responds when it receives a "bluetooth play" command?
That is, why does it select the player it selects and is that something we can modify?
Thanks for all enlightenment!

Google Music bug streaming bluetooth

So I have been using and loving Google music and my 5,000 songs on cloud. I have found an irritating bug and am not sure if anyone has the same problem.
I have a head unit in my vehicle that is capable of streaming media via Bluetooth. Anytime I end a call Google music turns back on even after closing it. I have X it out in the notification slide down menu. I even went into running apps and force closed it. Keep in mind before I make the phone call Google music is not on, not in the notification bar and not in recently opened apps. And magically call ends on Bluetooth, and phone restarts Google music and starts playing in my car!
I don't think this happens if I I use google music with my headphones.

Well it really depends on the system in your car. Most systems I have dealt with (Ford sync, Toyota, Chrysler) automatically resume whatever song is playing if connected for Bluetooth audio. If you do not want audio playing through the phone you can just pause it using a command on the steering wheel or on the radio itself.

Yes it is supposed to resume whatever song is playing. i have ford sync for almost two years now and was using Pandora streaming plenty. If I exit Pandora or let me be even more specific, pause a song before I make a phone call, when I end the call the song stays paused or Pandora stays closed until I tell it otherwise. This is not the case for Google music. I press pause then song continues once call ends. I quit the program before call, song continues, force close before call song continues....Technically there should not be any song playing when I told it to stop in the first place.

[Q] Stream music over bluetooth

Hi guys, I really hope someone can point me out in the right direction here.
I just bought my nexus and I love it, except one small thing.
Each time when I use my phone for streaming music over bluetooth to my car the music plays like a charm but when I turn the the car off the music keeps playing on my nexus and it never stops until I manually close the app.
The app turn off by itself or?
I´m using stock rom btw.
Thanx in advance.

I'm streaming music from google music via BT A2DP regularly in my car and the stock player always stops streaming/playing automatically as soon as the BT connection is lost = I turn off the car.

Suspected that it would work as you experience

Muisc player starts playing after bluetooth call ends

Hello everyone, I have a completley stock samsung s2x on telus. Everytime I end a call on bluetooth in my 2012 honda civic the built in music player in my phone starts to play automatically, sometimes I am streaming music and the music player still comes on and I get two different songs playing at the same time. I finally erased all my music files on my phone, any ideas.

I can't help with the issue, but what I can tell you is that Samsung's bluetooth stack is totally messed up. There are a number of issues associated with it.

My only suggestion would be to completely close the music apps, don't just hit pause and "home" back and just leave the application open. If hitting "back" doesnt close it, use the built in task manager to kill it.

[QUESTION] Google Play Music switches audio from headphones to speaker when unlocked

While playing music on my un-rooted Sprint Samsung Galaxy SIII, every time I unlock my phone the music switches from the headphones I have plugged in to the phone's speaker. When I un-plug and re-plug he headphones or pause and play the music, it switches back into the headphones. This issue is very debilitating as I am often listening to music in quiet places and it's embarrassing when my music starts blaring. Thanks for your help.

I have the opposite problem. When I listen to music on my headphones the music switches to the speakers when the phone locks. I guess you never figured this out. I know my problem is due to the lockscreen app "Widget Locker". When I deactivate it the problem goes away. Guess I'll head over to the widget locker thread and poke around. I'm on an S3 as well.
Edit:
I found a cool workaround by using the Tasker app. I made a profile which disables Widget Locker when i plug my headphones in and enables it when i unplug them. Seems to work pretty flawlessly.

Do you have gapless playback??
