Current pipewire versions do not seem to work well with chromium - tried with chromium from the official repo as well as with chromium105.0.5153.0 compiled by myself.
I’m on Chromium “103.0.5060.114 (Official Build) Arch Linux (64-bit)” from the Repository. I tried playing video from there and Firefox 102.0.1 (repository) at the same time (simultaneously) and am not experiencing this. Pipewire 0.3.54-1
Different sources you mean apps or physically routed from/to different sources (Line out and USB speakers simultaneously)?
No, I only assumed that this issue might be related. In the meantime, I noticed that any sound played (including notifications) from chromium, stutters here.
I’m on 5.18.10, no problem. I wonder if changes within the kernel versions affect something within your hardware—do you have specialized hardware, a specific DAC maybe?
