Hello
My diagnostics report number is: 1482044825
The left output and LFE sub channel on my Sonos Amp is not working properly. The problem started today after I did some rewiring around my house and reconnected the amp. Due to this problem I have tried hard resetting the Amp and the app, with no luck.
Left and LFE channel does not work with Line in. I have verified that my PC is not the problem as I tried a different amplifier and both channels worked. The only way to get both speakers working is if I run the amp in Mono mode, but I don’t want that. I want to use stereo.
The speakers are not the problem since I tried them on a different amp.
Both speakers work while using Spotify or any other streaming WITHIN the Sonos app, but the subwoofer output channel does not work in any mode I try.
I verified that the balance on both my PC and Sonos was on 0, so both channels should be working. Sonos AMP is simply not accepting the LEFT channel signal
I tried with different cables, made sure all cables were seated properly, but no luck.
The subwoofer is not problem as well. I tried on a different amp, tried a different cable, I put my finger at the end of the cable and the subwoofer was sounding normally.
My entire setup was working perfectly before today.
