I have a Sonos Connect, it had a high popping noise or scratching noise almost sounding like it would break the speakers, making it impossible to use.
I opened it and changed a few capacitors. This eliminated the popping/scratching noise, but now i only have sound in the left speaker. The right speaker is very low, but not zero. Using the equalizer, if I move all sound to the right I can hear it faintly. Left speaker works normally.
If I switch the cable (using rca analog), like red to white, i get the same problem but on the left speaker instead.
Clearly it's the analog out (red) line that is faulty.
I have tried several amplifiers so that is not the problem it's the sonos. But what to do?
