[pulseaudio-discuss] pulseaudio seg faults when switching to bluetooth sink on RPi3

Sun Mar 19 11:58:42 UTC 2017

Using pulseaudio-9.0 and bluez-5.43 and the RPi3 built-in bluetooth

After starting the bluetooth daemon, pairing with bluetooth headphones and setting them as an a2dp sink, attempting to switch the audio stream to Bluetooth results in a seg fault.

What would be the best way to troubleshoot this?

Bluetooth daemon and Bluetooth command logs attached.
