I was able to succeed till the step 3 and partial of step 4. I am able to connect to audio source. Once I start play song from A2DP mobile, my sound card settings disappears from the panel and pulse audio get disconnected. In /var/log/messages I see pulseaudio[1728]: ratelimit.c: 122 events suppressed pulseaudio[2190]: pid.c: Stale PID file, overwriting. pulseaudio[2198]: pid.c: Stale PID file, overwriting. What kind of debug traces do you need for this debugging? Can I send bluetoothd debug details. Will that help? Thanks, Nic Shen
