[LAU] pipewire problem - sounds like a bitcrusher (sometimes)

Hi, I've recently (not quite sure when it started) had trouble with Pipewire. In my setup, I use all the drop-in replacements for JACK, pulseaudio, alsa, etc. The problem is that sometimes, after a while, everything starts to sound like it has a bitcrusher/downsampling effect applied. A typical path to the problem would be: 1 - start a browser tab that plays audio, pause the audio (everything sounds as expected) 2 - then start a youtube video in another tab while leaving the original tab open 3 - close the second tab 4 - go back to the first one and continue playback (everyhing sounds like there's a downsampling effect applied). I usually have to restart the browser. But it's not only happening with browser applications. Muting and un-muting channels repeatedly in Ardour can create the same problem. I've observed this on two laptops, both running up-to-date Arch Linux with latest Pipewire, usually with the internal sound card. Does anyone have a hint on how to solve this? Best, Niklas
