Try turning the volume all the way down. If it still crackles
its the audio out IC. The resistor & cap may be a red herring.
At best its feeding B+ to part of the audio but then both
channels would be affected the same.
Also look for bad PC cons at the audio IC's, RCA & headphone jacks.
I will also check for a Sams but I dont have many that new.
