I tried nuking sys-audio, resetting audiovm to dom0, and testing. Speaker output works in dom0.
After recreating sys-audio (using the same template as before), setting audiovm again, and testng, still no sound from the built-in speakers.
Tested with bluetooth audio, sound works over bluetooth, so the issue is purely with the built-in speakers.
Alright, this is probably a device-specific issue, which is weird. This model of laptop has controller CS35L41, which didn't have kernel patches until 6.7 (which I waited for, and when I updated, that fixed the audio the first time). Those patches should still be in the kernel, so I'm not sure what additional troubleshooting I should try
