From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Likely what is happening is that the game is probing audio devices and triggering the mic on your headphones to get picked up. This switches them into the "headset" profile which has awful audio quality. I don't know why the UI isn't showing that, make sure you are checking while the game is running and the audio sounds bad.
If you want your headphone mic to work there is not much choice. There isn't a standard bluetooth profile with good audio and mic. If you never want to use your headphone mic you can probably configure some advanced settings in your audio manager (probably PulseAudio or PipeWire).
Thank you for the info. I won't need the mic, so I'll have a look at what I can tweak to prevent this 👍
Iirc there's a setting for Wireplumber (in case you're using PipeWire) to disable that behaviour when a BT mic is being picked up
Can you tell me what that setting is? I have the same issue as OP
edit: i think it's this
bluetooth.autoswitch-to-headset-profile = { description = "Whether to autoswitch to BT headset profile or not" type = "bool" default = true
Edit: for those looking at this thread changing that true to false works, although you do need to restart the computer
what was the filepath to this file?
i think its this:
/usr/share/wireplumber/wireplumber.conf
https://wiki.archlinux.org/title/Bluetooth_headset
Sections 3.3 or 3.4
I did 3.4 to disable the headset profiles cause generally it's ass
