[Verizon Samsung Galaxy S III] ViperRacer:
Ah ha! This got me to look in a different place for this. Looking at /system/etc/audio_policy.conf in the latest builds is missing an entry for a2dp. See the sections below from the 0122 and the 0218. I'll see about re-flashing the 0218 and modifying the conf file to see if it resolves the issue. Since this is a sync from CM I suppose I'll need to go over there to post the bug.

I'll check back once I've had a chance to re-flash and test.
