I have a Librem13v4 running NixOS. The issue I’m having is that during video calls (Google Meet), the audio stuttering is so bad that it’s basically impossible to hear what the other party is saying. The other party also reports an echo coming from my end. This happens on both Chrome and Firefox.

Any idea what could be causing this?
