Wireplumber version 0.5 no longer supports Lua configuration scripts (see Migrating configuration from 0.4 — WirePlumber 0.5.7 documentation), therefore it will ignore this type of script.

For newer versions, add a /usr/share/wireplumber/wireplumber.conf.d/51-fix-crackle.conf file (or /etc/wireplumber/wireplumber.conf.d/51-fix-crackle.conf to keep it out of /usr/ as @John_Flatness suggests) with the following:

monitor.alsa.rules = [
  {
    matches = [
      {
        node.name = "alsa_output.pci-0000_00_1f.3.analog-stereo"
      }
    ]
    actions = {
      update-props = {
        audio.format = "S16LE",
      }
    }
  }
]

Also, instead of restarting the computer, you can just restart PipeWire and Wireplumber:

systemctl --user restart pipewire.socket wireplumber.service

TIP: you can see debug information about PipeWire & Wireplumber with:

systemctl --user status pipewire{,-pulse} wireplumber

Other tip, to see the format of current playing audio:

cat /proc/asound/card0/pcm0p/sub0/hw_params

access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 1024
buffer_size: 32768
