Better attach logs after "D/A2dpAudioInterface( 890):
A2dpAudioStreamOut::set 80, 0, 0, 0", indicating seconds of activities
after you start the A2DP streaming but without audio. There usually
should be something printed out.
Losing audio would be either caused by a2dp_write failure or lengthy
pending (shown as CPU pegged, etc). BTW, can not see your Bluetooth
headset's name and media service related loggings. Did you filter them
out?
Sincerely,
Jackson
