A2DP - Automatic Stereo Audio

I have searched around XDA and haven't found a solution to this yet.
I have a wireless transmitter to play music in my car. When I turn bluetooth on it automatically turns on 'Hands-Free' but doesn't turn on 'Stereo Audio'.
Previously on my Kaiser (with a different car kit) turning on the transmitter set it up automatically.
I have tried AutoA2DP (from http://forum.xda-developers.com/showthread.php?t=530932) but I'm not sure it worked - it certainly hasn't achieved the effect I want (although it does seem to open Media Player when I connect now).
Anyone found a solution on the TP2?
Cheers,

I did have take a quick look at my TP2, because I had no problem with the connection. My car radio (Sony Xplod) gives 2 icons... 1 from the hands-free and the other of my Audio. I've looked in my settings for you, and found one option what must be checked. It's something like: Make a seperate connection for handfree and audio! (I'm guissing to that sentence becuase I have a dutch ROM!)
Hope it helped you!

EDIT:
Just did take a closer look into my car, and now it also didn't take the extra connection with my sterio audio. This is the solution:
Go to Com Manager
Press Setting
Press Bluetooth
Take the second tab
And tap than Sterio Audio
Now He's saying he's trying to make a connection e voila! Now it's playing music true your car audio!
(This is the way with TF3D2!'

Yes - I've been doing this every time I get in my car - I just wish there was a way of doing it automatically (and then preventing the message 'You can't control audio via this headset' or similar).

Hi,
Same problem in my car. Same car radio working with two (Sony Ericsson) phones I used before. They always connected immediately (both 'Hands-Free' + 'Stereo Audio). Strange that the TP2 is not comfortable with this simple task. Indeed, I think the option "Connect separately to Bluetooth hands-free and stereo audio services" should be unchecked but despite this option, the TP2 is still waiting for the appropriate tap. Going to BT settings and tapping 'Stereo Audio' each and every time is frustrating and uncomfortable.

Added subscription to this topic.
I'm a bit frustrated too with the AD2P auto connect problem.
I have a Sony MEX-BT3700U Car radio.
When I sit in my car, the handsfree function connects automatically with no hassle.
But not the Stereo Audio (A2DP) function. I connect it via the Bluetooth settings. After that it works great.
The problem is I'm always focused to activate AD2P manually first before I drive and forget that I have yet to start the car. So I have to start over. Going to settings > Bluetooth Settings etc. etc. ANNOYING!
So. I tried A2DP Toggle in combination with A2DP Auto Connect. Doesn't work.
Went searching for hours... But nothing. Think it has todo with the different BT Stack compared to other HTC's.
Still hoping for a solution.

@Ramsfan_Jim: which wireless transmitter are you using? I'm thinking of buying one to use w/my TP2. My factory head unit (VW Monsoon) doesn't support bluetooth.

I originally used a Venturi Mini - which had the advantage that it automatically set up handsfree & audio transmission as soon as I turned it on, but unfortunately it broke (repeatedly) with regular use.
I now use this one http://cgi.ebay.co.uk/Car-MP3-FM-Transmitter-Bluetooth-Handfree-w-2-Remotes_W0QQitemZ250445424484QQcmdZViewItemQQptZLH_DefaultDomain_3?hash=item3a4fb5e764&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A6%7C72%3A1683%7C293%3A7%7C294%3A25 which is much sturdier - and seems to have a stronger signal. However, I have to change the bluetooth settings on the TP2 to enable Stereo Audio each time I connect.
Warning - this is a much bigger device, so dependent on where your cigarette lighter is in the car, it may get in the way. I had to buy an extension lead to move it so I could use the gearstick!

Newsflash.
Found out how to auto connect to my bluetooth car radio with my TP2.
I have a radio channel bar (or whatever it's called in english) from one to six. There's a "pause/play" description small above the number five. I accidentally pressed it and it suddenly connected my phone through AD2P.
So just press play and it gets connected. So no software needed for me.

I don't use a BT car radio but I do have a stereo BT and a regular BT headset. The stereo BT has both Handsfree and A2DP profiles. But since I use the A2DP only, in my Kaiser under BT Services I unchecked the Handsfree profile and now my stereo BT autoconnects every time.

ChriX84: thanx, very interesting information, will try it tonight in my car !
Another interesting info (might be useful in terms of a .cab file preparation...): a "BT Mono" (i.e. not Stereo Audio (A2DP)) with a very low volume signal is obtained (in my car radio at least) when pressing the "Play" button on the media player (Core or WMP) while still having Stereo Audio option switched off under the BT settings.

This worked for me too. Was bugging me to the extent where I wasn't bothering streaming audio any more!
Nice tip

I always burned new mp3 cd's or connected my mp3player/phone through a aux-cable.
Bluetooth Stereo Music is a huge step forward for me. The ease of using one device for everything. Calling, playing music without any cables. Thank god for that invention.

What exactly is a radio channel bar? Do you mean like a media widget or radio widget?
Personally this a2dp bug is a deal breaker for me. I primarily use my device for audio streaming.

Yeah where can you find this?

The bar with all the channel buttons. 1,2,3,4,5 etc.
Above or under those buttons there are little symbols with play/pause etc.

HTC paired with car -> No sound for the GPS!!!

Hi!,
I have a HTC Touch Pro 2 that I usually pair, via bluetooth, with my car. When this connection is made, a message shows up on the HTC’s screen informing that the connection does not assure some sound functions. Nevertheless, all the phone functions work great.
The problem is the gps. I bought a few days ago the gps software NDrive v10, and after a few tests I realised that when the HTC is paired with the car, there is no sound from the NDrive. I open NDrive and I can’t hear a single instruction!
The solution is turning off the bluetooth so I can hear the instructions from the NDrive, but this way I have no handsfree system for the phone…
Is there any way of solving this problem, having the HTC paired with the car, and at the same time, hearing the instructions from the NDrive?
Thanks!
MM

Are you pairing both Hands-free and Stereo BT profiles when you connect to the car? Maybe that program requires the Stereo profile to route sound through your system. Otherwise, only phone functions will be routed. My phone automatically pairs the Hands-free profile when I get in the car, but if I want to stream music from the phone to my car stereo I have to manually start the Stereo BT profile.

when you mentioned the car's BT profile I went and check the car menus, and I found one (that I missed previously) that gives the option of listening to the sounds from the HTC. Whether it is music or gps!
But I still have a small question. When the menu that I mentioned above is select I can only listen to sounds from the HTC. This means that when I'm listening to the gps I can't hear radio or cd player from the car...
Nevertheless, thanks for the help!

On the HTC you can pair the phone and the stereo. If you disable the stereo on the HTC, that may get you what you are after.

That's because the radio can only have one input active at a time, and when the phone is connec ted via BT in stereo mode, that's all it can handle. It doesn't matter if you're streaming music or GPS directions from the phone.

[Q] Inc and SYNC (Ford)?

Can't get the audio to play through the car.
Calls work fine, connects fine...but with winamp playing and car on Aux Input, no sound comes through the car.
I couldn't find any settings to switch audio output. Phone plays no sound and nothing is heard from the car either.
Anyone else experience this an have a remedy?
Thanks!

Is this through a cable or bluetooth?

Bluetooth..sorry

I know it's a stupid question, but have you paired the Dinc properly? Have you been able to make phone calls with the Incredible over Bluetooth and Sync? What year/model Ford?
One issue I've had is when you have >2000 contacts and you download them to Sync. That breaks connectivity incessently. Solution is to NOT download phonebook, only those handful of contacts (family, office, etc.) you believe you'll need regularly.

never downloaded the phonebook and its worked the couple times i've used it. 2011 fusion. Seems to pair fine, just can't figure out how to properly play music.

Pair & Play
I can assist - I use Ford Sync w/ my Incredible. Works seamlessly, one of my favorite features!
Make sure vehicle & device is paired successfully - follow instructions in manual to do that.
I press the speak button, say "Bluetooth Audio", open my music player on the Incredible and the music plays through the car speakers - just like voice BT.
When playing Angry Birds or other things on the device, you hear game output sound through the car speakers.
Note that when you flash other ROMs, your BT pairing(s) for Ford Sync, ear-based BT devices, etc will go away.
Solution? Titanium Backup - backup those pairings, flash, restore BT pairings.

Bluetooth in car...phone and/or audio???

Hey all
I have had a lot of trouble with my Galaxy's bluetooth connecting with the system in my Infiniti M37x
I now am able to have it so everytime I get into my car, the phone's "phone" bluetooth connects automatically, I can use the hands free system to make and receive calls AND the phonebook is downloaded into the system as well. Works just GREAT! I can talk on the phone and I have my contacts there. All hands free.
But......
that is only if I pair it to the phone part of the Galaxy.
If I also pair it to the audio device, then the troubles begin.
If I were to pair the audio to my car, the music sounds great...but once I turn off the car and leave, come back, the car won't recognize the phone part. Even if I go to BLUETOOTH settings, and click the little button, it won't stay or connect to my car.
This worked great with my EVO using Gingerbread.
Is this an ICS thing?
Are there any apps that would allow me to just leave the phone as the default car connection and if I want to listen to music, just click something to switch it over to audio part?
Whenever pair to the audio and I use the audio bluetooth connection, I have to unpair and start all over to get the phone to connect.
Hopefully this makes sense. Any advice would be helpful.

This is a Samsung thing (and I hate their phones because of this)
To have this function correctly, you need to enter car dock mode. To enter car dock mode, you need a samsung car dock.
If my phone is docked, I can stream music, receive calls, etc, all work great.
If I leave it in my pocket and I stream music and receive a call, the audio comes through the phone, and not through bluetooth.
My E4GT was like this. I opened an issue with Samsung to which they replied "Working as designed"
No other phones work like this, only Samsung and their ****ty bluetooth switching.
I think you can also solve this by going AOSP or AOKP.

I have no issue with my s3 when connecting to audio or phone. and im able to answer calls, and play music no problem

How did you pair both? Do you have to switch between the two?

I am also having this same problem but only after flashing a customer ROM. With the costume ROM the phone will connect phone and I can make calls no problem but I can not get music to stream to my car stereo no matter what I do with the costume ROM when back to stock just to verify this and I have no problems streaming music on stock ROM or making calls via Bluetooth.

Sprint GS3 horrible in car
The first two days the phone worked great. Now it connects but the sound is noisy and unintelligible from either end. I don't know what changed. anyone can help me on this? can I stream music through bluetooth if it ever starts working again?

are you running the stock software not modded in any way?

Car Bluetooth

Hey guys, i got a question.
I would like to purchase the watch but i am doubting something. If my watch would be connected to my phone and i step into my car and normally my phone auto-connect over bluetooth to my car audio system. Would it still do that? And i'm i able to pick music on my watch in the car, example Spotify library, to play on my car audio.

The Bluetooth should work just fine. I don't have it with a car Bluetooth but when using the Bluetooth headphones it doesn't have any issue at all because both link directly to the phone.
The music controls are another thing, you can use it as a remote to play, pause, skip or go back through the tracks but it doesn't let you select whatever you want directly from the phone(selecting playlists or songs from them).
If you download playlists on the watch because you have premium you can go through them and select the songs just fine, but then you wouldn't be using the phone to play the music, so you should check if the car would let you have two devices connected at the same time if you want the phone linked for something else.
Tldr: Remote or standalone Bluetooth music yes, total control of the phone app no.

Ive been having issues with that as well. Do you have android auto in your car? If so, you need to go into AA options on your phone and go to quick connect and only have your phone connect.

I can confirm that you can still use BT on your car and have it connect at the same time with your watch. If you are having issue connecting just go to your car's BT settings and force the connection and it should connect to your phone for media. I use my watch when I'm driving to change a song without having to move my hand from the steering wheel.

Let me add to this that, at least for me, it is *not* possible to have the watch connected as a handsfree device to the phone together with the car kit. So the watch is connected, but I can't answer calls with it if I want the phone to connect to the carkit. It (the phone) simply rejects that request if the watch is connected.

This is why I don't want a smart watch. Only because when I sit in my car it will not connect to car and disable on watch.
