I do not know where else to put this since there seems to be no section on GitLab to submit config fixes.
My sound has been cutting out for all applications using PulseAudio/ALSA when closing just one of them. The suspend fix for Garuda’s WirePlumber is made using LUA, but since version 0.5 WirePlumber no longer supports LUA. The fix from Arch Wiki needs to be implamented if it’s not already been done so. In my case it was not applied with the recent update to KDE 6.
