I found these in dmesg, but I have no idea what it means exactly:

 [   19.427576] snd_cs46xx 0000:01:0a.0: Direct firmware load for cs46xx/cwc4630 failed with error -2 [   19.427587] snd_cs46xx 0000:01:0a.0: firmware load error [cwc4630] [   19.429428] snd_cs46xx: probe of 0000:01:0a.0 failed with error -2
