Hi, I have a problem with my bluetooth headphones, or maybe with the bluetooth subsystem.
The symptoms are these: especially during long videocalls (with Google Meet but also with other software) sometimes audio stops abruptly.
If I change the output to my external speakers, I can hear audio.
Sometimes I can get back audio in my headphones simply by changing the output back immediately. More often, I have to wait for 30 seconds or a minute, and then change back.
Usually, initially it works for a long time (like half an hour), then, when it starts happening, it repeats more often (like ten minutes, but not a with regular pattern).
I have had this problem for a long time (more than a year).
Is there anybody else seeing this problem?
Thank you both for your suggestions! @marel I would have never thought about interactions with wifi!
I have my wifi router very near, and it’s using both 2G and 5G.
I’ll disable 2G and see what happens!
A few minutes later… unfortunately I just found out that this is not a viable solution.
I have too many devices that can only connect to the 2,4Ghz wifi, unfortunately.
And they are not devices that can be upgraded
I’ll have to figure out another way. Maybe positioning the router elsewhere.
Apparently this does not work. I get: Invalid command in menu main: monitor
My bluetoothctl is version 5.79. bluetoothctl help show this (weirdly, it shows the “monitor” option twice):

I see that I can enter the “monitor” submenu, but then I’m lost as how to continue from there.
