Okay, so I’ve found this issue that seems to be describing my issue (although I’m not 100% sure if it’s applicable).
Since it was closed and fixed, I assumed perhaps it was that my audio related firmware was out of date, I went looking for that and found this solution. Specifically, I applied the sudo pacman -S sof-firmware alsa-ucm-conf which unfortunately didn’t do anything. I also tried some of the config options described on the Arch wiki, but (unless I messed up somewhere), nothing changed (I’m on the c930, whereas that Arch Wiki section was for the c940, the BIOS fix they were talking about only applies to c940).
I additionally tried to install the sof 1.9.2 update described by the readme on the sof-bin GitHub project to no avail (I tried this before the command above).
If anyone knows where to go from here, it’d much appreciated.
