Bug Description
Same issue already been reported at https:/
Below is the my bug description, more details can be found on above github link:
Bluetooth connection will lost after several minutes audio playback, and the program will lockup when try to stop the stream.
The log of dmesg:
Bluetooth: hci1: hardware error 0x00
Bluetooth: hci1: command 0x1003 tx timeout
Bluetooth: hci1: command 0x1001 tx timeout
Bluetooth: hci1: command 0x1009 tx timeout
The log of bluealsa:
bluealsa: D: ../../src/
bluealsa: E: Couldn't release transport: GDBus.Error:

I was using bluez-alsa on a Raspberry Pi 3B+ running latest Ubuntu-mate, 18.04.4 LTS (GNU/Linux 4.15.0-1054-raspi2 armv7l). The Bluez version is 5.48 from the depot originally. I have tried to upgrade Bluez to 5.52, but can not fix the problem.
When the issue happens, bluetooth will go off and stop responding completely. And I can not turn on bluetooth anymore, below is the output of bluetoothctl:
[bluetooth]# power on
Failed to set power on: org.bluez.
Restarting bluetooth service or bluealsa will also not help, the only way to recover is a reboot.

I have tried to build and install the latest rpi-4.19.y branch of https:/ /github. com/raspberrypi /linux on My 3B+ running Ubuntu-Mate 18.04. And confirm that it fixed the Bluetooth problem. I leave it play audio overnight and cannot see an disconnection. /github. com/raspberrypi /linux/ commit/ 65aa6ec0faaa012 508489886ac357c bb86cdb9a4
