I recently switched my laptop to Arch and have been encountering some perplexing audio issues. I listen to music on a set of speakers connected to my laptop by an Apple USBC to 3.5mm DAC. I have used this hardware setup on multiple other systems with no problems. After some variable number of minutes of successful playback, the music will be replaced with extremely loud white noise. I have found that if I turn my volume down (say from 100% to 20%), the music is actually still playing; it's as though a massive gain factor has been suddenly applied. After some variable amount of time at the low volume setting, the music will suddenly become extremely quiet and I have to turn the volume back up to 100%. There does not seem to be any consistent entry in journalctl that occurs when these volume jumps happen, but the last one was accompanied by

I use Pipewire + Wireplumber and the closest thing I've found to a lead is this pipewire issue. However, the discussion there seems to suggest that the problem lies somewhere in the USB stack rather than in Pipewire itself. I don't encounter this problem playing audio over bluetooth.
Are there any troubleshooting steps I could take to try and shed further light on this? Thanks in advance
