Only 2 audio profiles for Bluetooth headphones on KDE

tenid · 05-13-2022, 03:00 AM

I'm running gentoo KDE on my potato PC because other distributions would run very slowly.

So, I cant get audio to be decent quality, When I go to choose audio profile I get only 2 options:
(HSP/HFP) and (HSP/HFP, codec CVSD)
I went around forums to see if there is any fix to it and found that changing MultiProfile to multiple in /bluetooth/main.config would do the trick
I tried it, and it worked after restarting bluetooth had many more options to pick from. I then rebooted the PC and those audio profiles were no longer there, I have no idea what i'm doing wrong and feel hopeless. The headphones, i got for my birthday and want to try them out.

Sorry for my bad english and thank you!

I am not sure I can help as I do not use a BT headphones on my PC

I think you are asking for better profile such as showing here
https://wiki.archlinux.org/title/blu...set_to_HSP/HFP

just above that link is this "shortened quote"

HFP support is not stable and may cause glitches

this is the opposite of your research to

fix to it and found that changing MultiProfile to multiple in /bluetooth/main.config

so I think you actually need to try A2DP profile

for an explanation of profiles try

A2DP (Advanced Audio Distribution Profile) - high-quality audio playback, appropriate for e.g. listening to music.
HSP (HeadSet Profile) - phone-quality audio playback and recording, appropriate for phone calls.
HFP (Hands-Free Profile) - same as HSP, but with additional functionality for managing phone calls.
