[Solved] [Hardware] Bluetooh audio output stops working after a few minutes

#1 Post by scmorell »

Hi all,

I have experienced this for a hwile now. I use Debian 5.10.0-23-amd64.

I have a Bluetooth headset and using blueman I can connect it successfully.

Audio playback will work and then stop after a while. How can I find the cause of this problem?

With USB headset the issue is not present.

kr,

Ok, I will try. Thanks. And I make sure to take this as a reminder to search more thoroughly next time

It does not solve the problem, i.e. issue persists.
It happens this way:
1. Video has no sound suddenly (playback resumes).
2. Bluetooth headset disconnects
3. Bluetooth headset reconnects after a few seconds
4. Playback resumes.

This does not happen with the same Bluetooh headset on Android, also not on another Windows machine I use.

Check if the module parameter has been applied:

Code: Select all

cat /sys/module/iwlwifi/parameters/bt_coex_active

Ok, I did

Code: Select all

sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=N"
Then I rebooted.

Now, when I input

Code: Select all

cat /sys/module/iwlwifi/parameters/bt_coex_active
It returns

Code: Select all

N
I thought a workaround would be to turn off Wifi. But it does not help. Issue still persists.

I have upgraded to Debian 12. It seems to work for now.

Further info for troubleshooting / debugging can be found on Blueman project Github page.
