Bluetooth headset works for couple seconds only

Hi everyone. I'm trying to resolve the flowing issue:

I've successfully paired up and connected my bluetooth headset (airpods) via bluetoothctl, and sound device has appeared in pulseaudio (it's visible at pavucontrol at least).
Right after connection it all goes well for 1-3 seconds, sound is played, but after these several moments it just mutes itself.
In pavucontrol I see that sound really goes to bluetooth headset (I see volume level bar dancing).

BT device:

Bus 001 Device 002: ID 05ac:8290 Apple, Inc. Bluetooth Host Controller

Any ideas?

Also, every time I restart pulseaudio (pulseaudio -k) and connect to headset sound always appears and than disappears again.

Do you have bluetooth enabled in systemd?

c00ter, thank you for your interest.

Yes, I have bluetooth.service enabled:

Re: Bluetooth headset works for couple seconds only

This "sounds" like a hardware power-saving issue and, at this point, beyond my ability to troubleshoot. Googling your issue leads to a plethora of responses commonly indicating; A) interference from another device, B) computer hardware power-saving settings in the EFI/BIOS firmware, C) power-savings settings of the headphones themselves. In my Dell Intel/Intel laptop it is necessary to use a modprobe.d configuration file with the settings "options snd_hda_intel power_save=0" in order to keep my remote BT speakers connected in some circumstances.

regards and best of luck

Yes, I've came up to the similar conclusion, thank you. Would investigate in this direction.

Re: Bluetooth headset works for couple seconds only

Does setting enable_autosuspend=0 on the btusb module help?
