filter-chain distorts audio after >120 seconds playback
I have a modified sink-eq6 filter-chain installed in ~/.config/pipewire/pipewire.conf.d/ along with using [ 44100, 48000, 96000 ] as available rates.
With pipewire 0.3.52 this worked reasonably well (pointing the hesuvi-7.1 filter's output node.target to sink-eq6 results in at least four mod.filter-chain "no node available" error messages in the journal on startup, but it works once you start playback).
With pipewire 0.3.56 playing 44110hz audio with the same rate on the filter and output, it works for approx 121 seconds then distorts with repeated audio skips/pops (tested Rhythmbox and mpv both using PulseAudio output). Pausing a song then playing results in ~121 seconds playback then popping audio again. pw-top shows 120 errors in the filter chain and output devices, but they don't accumulate while playing, and no crashes.
Disabling the filter results in normal playback directly to hardware so I don't think it's an output/driver bug. OS is Arch and kernel is 5.18.12-arch1.
