Public bug reported: Right speaker crackles while left speaker is intact.
Tried many quirks including those posted here -> https://ubuntuforums.org/showthread.php?t=2464361 (That OP is me only). I also tried to position quirk as mentioned in troubleshooting guide -- didn't work. I am yet to try to use a live boot and see if problem is hardware or not.
