Bluetooth microphone not detected
Probably a bluetooth issue.
Screenshot translation (my system is in German): The upper part is the output devices, and I am able to select my bluetooth headsets. The bottom part is the input devices, and my headset is missing.
This is not a headset issue, since neither my Sony nor my Sennheiser headset is working.
This is probably a bluetooth issue since my cable-connected Jabra Evolve 2s are able to use the microphone.

Did you disable it before to prevent audio profile switching? See if it's set to enabled with
ujust toggle-bt-mic

I just confirmed that on my Windows laptop, the headset's microphone is working without issues
Solution
Did you disable it before to prevent audio profile switching? See if it's set to enabled with
ujust toggle-bt-mic
Should it be enabled or disabled?
Thank you for the quick response btw!
It's disabled so it's not inhibiting your mic.
I just enabled it and disabled it again and now it's working magically!
Ah nice. It configures pipewire, so it got set to the default probably after disabeling it.
Before marking this as resolved: Could you quickly explain how you knew what to look for? I mean, it was disabled but clearly not really
I do remember having had issues in the past with discord, and I modified the
/etc/bluetooth/main.conf
like this:
(top of the file)
I did this because Discord keeps forcing the lowest-quality profile (HSP/HFP, Codec mSBC or Codec CVSD)... I was playing around with configs to try to fix this
Anyway, do you happen to coincidentally have an idea why Discord forces the low-quality bluetooth profile?It's a common issue on linux that bluetooth headsets switch to shitty mode when launching programs with mic support. On bazzite the ujust script is the easy mode disable the mic option.
Here's the script:
Cool! Works like a charm
Do you happen to know of any possibility to use the mic in non-shitty mode (high-quality audio at the same time as having a usable mic)?
Not possible over bluetooth because of used codecs. Only wireless dongles will do that.
Good to know! Thank you for helping me!
Out of interest, and tangentally related to the topic: How are wireplumber, pulseaudio and pipewire different and how do they interact with each other?
E.g. I have to have a .alsoftrc file in my home with
otherwise Minecraft won't start. But like, pulseaudio and pipewire are both audio servers (whatever that means, I'm not that kind of dev), yet why isn't "pipe[wire]" available as an option there?
Not expecting an answer if this is too off-topic for bazzite-help
Afaik, bazzite only comes with pipewire. Pipewire is however backward compatible with pulse etc. Wireplumber is a configuration tool for pipewire. The linux audio stack is a hot mess. It does work way better than when we were on pulse. If you want to learn the ins and outs, archwiki is a goldmine: https://wiki.archlinux.org/title/Sound_system
