Reassigned to pulseaudio. Bluetooth audio is a software feature implemented in pulseaudio, not in bluez.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

There are two problems in your logs that might be relevant:

1. Timeouts:

[1666806.664899] Bluetooth: hci0: command 0x200c tx timeout
[1666808.680839] Bluetooth: hci0: command 0x0401 tx timeout

2. BlueZ crashed:

[1666867.068257] bluetoothd[9515]: segfault at 0 ip 0000556e0bc36576 sp 00007fff1afb5c40 error 4 in bluetoothd[556e0bbcd000+f3000]

But since this bug is a couple of years old already, please tell us if you still experience it.
