Fixing Crackling/Buzzing Audio on Pipewire

Quick potential fix for crackling/buzzing audio issues

Check values of these two files:

cat /sys/class/rtc/rtc0/max_user_freq
cat /proc/sys/dev/hpet/max-user-freq

If they have defaulted back to 64 for whatever resaon, that's likely causing your crackling. You can fix it by running the following commands

sudo -i
echo 2048 > /sys/class/rtc/rtc0/max_user_freq
echo 2048 > /proc/sys/dev/hpet/max-user-freq

then restart pipewire with

systemctl --user restart pipewire.service

(or you can reboot if that's easier)

This should fix the crackling!
