I encounter the same issue from time to time. Almost consistently reproducible when I update the kernel and the VirtualBox driver needs to be recompiled (and there's no cap for that process that it should use max X% of CPU).
As pipewire is within the user session I would assume higher system load would induce some latency and cause the jitterness.
But in the end I'm just making assumptions, and correlating.
- mkdirp 5y agoThis sounds about correct. I had a similar hunch, but I noticed it correlating to high memory instead (could be just a symptom, perhaps it was doing more swapping?). I increased my swap partition, which made it happen less often. It could be very well be the CPU.
- nitrogen 5y agoDistros should really be setting niceness levels on more processes by default, especially background software updates. And anything audio-related really needs to be at a realtime priority.
- Arnavion 5y agoPipeWire, just like PulseAudio, uses rtkit if available. Your distro may have made it an optional dependency, so you may not have it installed.
