I have a problem with my bluetooth headphones. When I power up my computer, connect my bluetooth headphones it works as ti should, but if I in a couple of minutes don’t listen to anything and then plays a youtube video the sound chops. To get it working again I have to either disconnect the computer or power off and turn on the headphones again.

An other thing I experience is, sometimes when I don’t use bluetooth it deactivates and the only way I can get it running again is to restart the computer.

First I thought it was a failure in my debian 9 because when I boot in to Windows 10 everything is fine. I then searched the net, it seams no one else has the same fail. Then I installed CentOS 8, same result. I hope some of you have an idea of what is wrong and can help me.

I think it has something to do with the driver but I’m not sure.

My system is a Acer Aspire E5-571 the Network/bluetooth controller is a Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)

Could be a powersaving issue.

Is there a particular reason you are running stretch, which is mostly EOL?
Are the headphones newer than stretch's release date?

The only reason I use stretch is because I have been to lazy to upgrade.
The headset is from March 2019 so yes thay are newer than stretch release date.

The pc has no power saving as far as i can see.

Any other suggestions?

How do you know that? Usually wifi and bluetooth have power saving options by default.
