Current pipewire versions do not seem to work well with chromium - tried with chromium from the official repo as well as with chromium 105.0.5153.0 compiled by myself.
See Audio stutters when playing YouTube videos in Chromium for details.
Amendment: Possibly related to Heavy stuttering when more than one audio source is playing (regression started in 0.3.53) (#2525) · Issues · PipeWire / pipewire · GitLab although Firefox does not seem to be affected on my machine.
