The sound changes when LOUDNESS is touched, but there is a lot of crackling. The sound changes when BLANCE is touched, but there is a lot of crackling. The sound seems to change when the BASS dial is switched to the R side. I can't tell if it's changing on the L side because no sound is coming out.
