Hi guys,
I got a thinkpad x1c gen 9 running 13.2 release, and having same issue, the sound is small and with mpv I can get it bigger like set to 200%, but the quality of that audio sucks.
Did any one of you managed to get your speaker work normally?
 
I solved it, this is the config I changed. And with this I got the headphone jack to work too(but only output), and it will automatically switch to headphone when pluged in.
