It was annoying enough I saved it, I highly recommend starting some sort of docs setup so future you can remember how you fixed things. This fixed it for me, granted I was on pop but both Ubuntu based so same layers underneath.

Audio Crackling

You can fix this by increasing the minimum audio buffer size, which, in turn, will increase the overall audio latency.

It's not good for real-time professional audio recording, but it won't hurt the general gaming and multimedia experience unless you use a very high value to the point it leads to a noticeable desync with video. Test with a greater minimum quantum

This takes effect immediately, but it won't persist across reboots.

This worked for me

pw-metadata -n settings 0 clock.min-quantum 2048

Increasing the minimum quantum permanently

The default is 1024.

cat << EOF > ~/.config/pipewire/pipewire.conf.d/fix-crackle.conf context.properties = { default.clock.min-quantum = 2048 } EOF
systemctl --user restart pipewire wireplumber

You can revert this by just deleting the file. Alternative method

This will improve the handling of low-latency audio at the expense of overall higher CPU usage and with that, power usage.

sudo kernelstub -a threadirqs reboot
