Crackling only from left speaker

Hi all! I brought my Dell XPS 9710 out of sleep last night and found the speakers were buzzing and crackling and giving just terrible garbage (no updates or anything; had recently restarted before putting the laptop to sleep, and everything was working fine).
Anyways, I tried the fix from t/buzzing-sound-random-crack-from-speakers/112208/22 (can’t insert links sorry =/) and it fixed the buzzing/crackling: but only for the right speaker. The left has remained unchanged. I’m on KDE, and in the audio menu in system settings when I test both speakers solo the right speaker is perfect and the left is garbage.

I also tried upgrading the kernel to 5.18 from 5.15 to no avail.

I also tried the switch to pipewire as described at t/popping-cracking-sound/114409 (still not allowed to insert links) and nothing changed.

I also already have the sof-firmware package installed.

Any ideas on what’s going on? I’d appreciate any help!

Here’s my inxi:
