Hi ! I have a big problem with the sound quality. When I turn on the c64 r mk2, there is like a snap. When there is music, the sounds seem to be muffled and there is noise. I tried with 3 different sids (two 6581 and one 8580) and no change! I used several different power supplies 12v 1.6A and 12v 3A but no change either.
Do you know that issue ?
