I have a ASUS B760-I ITX mainboard and according to alsa-info it seems the onboard audio chip is a Realtek ALC1220. However, if I record my voice, it really sounds akward, extremely loud and not normal. Very different from the normal behaviour I had in Windows 11.
Does anyone how what Linux driver I need for that?
If you open up alsa-mixer, and hit f6, what options come up? As far as I'm aware this is a fairly standard soundcard. I'm more wondering if the issue is that alsa has accidentally screwed some settings up somehow.
Looking at your alsamixer screenshot:
You have Rear Mic [MM] i.e. muted, but its Boost set 100%.
Unmute that, by panning across to that channel and hit "M" key.
I would reduce Boost to 0% once you have done that, at least as a start.]
You have Front Mic [MM] i.e. muted.
Unmute that, by panning across to that channel and hit "M" key.
See if any of those changes help.
You may have to play a few permutations and combinations one at a time.
If you find an alsamixer setting that works, save it using:
