UPDATE: The connection problem turns out to be related to AVRCP, not A2DP. For some reason, the phone will connect to the A2DP device perfectly (with AVRCP) if the phone is awake when the A2DP device is powered on. If the phone is sleeping when the A2DP device is powered on, the connection process is different and AVRCP is lost. A2DP will be connected, though.
See this thread:
http://code.google.com/p/cyanogenmod/issues/detail?id=611
So, I'm still having problems with getting a reliable AVRCP and A2DP connection with Cyanogenmod 4.2.7.1 on my G1.
Here is a log from a successful connection:

Disabled phone audio, and now only have A2DP connection. AVRCP looks fine in log, but doesn't work at all:

I had a similar problem with my Motorola S9-HD. It was working well, but stopped working during a recent update. The key symptom (besides the music coming out the phone speaker instead of the headset), was that when I would long press on the bluetooth device and view the options, only the phone profile was listed.
ReplyDeleteI turned off bluetooth and ran fix_permissions from the terminal emulator. Then after re-pairing the device when I selected options it listed the media profile, which was not selected. After I selected the checkbox, everything works great.
Hope this helps.
Thanks for the tip. As it turned out, my problem was concerned with AVRCP (the remote control media buttons), not A2DP. Specifically, the AVRCP connection is not setup when a paired Bluetooth device is powered on, and the phone is sleeping. Everything is perfect if the phone is awake when the bluetooth device is switched on. Does this work for you: Phone is sleeping, turn on your bluetooth device, then press play on the device (not on the phone). Does it work?
ReplyDeleteIf you are at all curious, I've got the pertinent parts of the logs here:
http://benkrasnow.blogspot.com/2009/12/bluetooth-avrcp-failure.html
I had the issue where: after I updated the ROM to Cyanogen 5.0.7, I was able to connect to my parrot bluetooth system, but it wasn't pulling the Address book or the call log. After following the advice from Anonymous (about fix_permissions), it worked properly.
