You are probably both right, I don't know but I would like to know a
little more how you came to this conclusion.
been testing it a lot, over every kernel-rt patch and pipewire release,
currently on 6.2-rc7-rt1 and pipewire 0.3.65.
pipewire's scheduling is allegedly based on s/w timers and not on h/w
irqs like jack/alsa; it's just more prone to xruns when under a
preempt_rt kernel and buffer-sizes (or quantum) lower than 1024
frames/period.
overall, vanilla preempt aka low-latency kernels, seem to work better in
this regard;
