Sound stream reference Picasso (blue board) problem still having the low sound from 1 channel. It got fixed but came back but this time I noticed something when I have the rca cable plugged into rear channel with no speakers hooked up instead 2 speakers are hooked up to the front channels instead I hear low sound coming from the front channels which doesn't have RCA hooked to them. If I was to reverse this same thing happens. Would this most likely be a switch problem? Or something died or broken trace. Thanks.
