I get the audio crackle also, been trying to figure it out for a while. Some people seem to have solved it by disabling power saving on the audio card. Didn’t work for me but might work for you.
cat /sys/module/snd_hda_intel/parameters/powersave
If it returns a “1” then power save is active

It’s been an unfortunately difficult problem for me to troubleshoot since it only happens occasionally. I appreciate the help though, I’ll give disabling it a shot (it was enabled.)
