[SOLVED] Pipewire audio is constantly crackling

Hey everyone :-)

I migrated from Debian to Arch around six months ago, and haven't had any serious audio issues until around a week ago, when my audio started to crackle and I have been unable to determine what the cause was. I've tried adding

load-module module-udev-detect tsched=0

to

/etc/pulse/default.pa

as suggested in the Arch wiki, but it doesn't seemed to have had any effect. I've looked at a number of other Arch forum posts, but I'm not sure what I should try, as the issues people are discussing don't seem to line up with mine, which is crackling every second or two. But I am happy to try anything because as things stand any media playback is just un-listenable.

Pipewire is constantly logging the following in systemd during playback when I have a couple speakers connect to a null sink.

May 13 11:41:12 desktop-0 pipewire[5224]: spa.alsa: front:5p: follower avail:35 delay:35 target:768 thr:512, resync (14 suppressed)

However, if I cut the links to the null sink the audio crackling is still present when using any output device as the default output, so I don't know if that is pointing to pipewire-pulse as being the issue?

This is a new desktop PC with high end specs and memory and CPU usage are not above 30-50%, so I don't think its being caused by hardware performance issues.

UPDATE:
After spending all day troubleshooting, it appears that it may be OpenRGB of all things. I installed it months ago, but only set it up recently.
