Package: fluidsynth
Version: 2.4.4+dfsg-1
Severity: important

Dear Maintainer,

It has been reported by several other users on the pipwire page (reference pipewire bug #1100943) that fluidsynth is causing dramatic audio distortion. Audio will play slightly out of sync/behind time, and exhibits a very loud crackling. 

Restarting the fluidsynth service (systemctl --user restart pipewire.service) abates the problem for each boot, but only uninstalling fluidsynth causes the problem to go away completely. 

Further, this problem only seems to occur over either wired headphones or HDMI/DP audio. Using bluetooth headphones seems to avoid the distortion problem. 

So far I have noticed this exact issue on two seperate machines/sound cards both using fluidsynth 2.4.4 and pipewire 1.4.2-1. The issue has persisted for the last several months on earlier versions of both packages as well.
