I have 2 hard wired non-Sonos speakers that were working fine for almost a year and then one stopped working. I reset the amp and then the one that wasn't working started to work and the other was silent. On my app in shows no line-in connected but I checked all of the connections. Any ideas?
What do you mean by “reset”. I don’t recommend a Factory Reset without further consult. “Reboot” by simply removing power is OK.
Check the connections again. Your issue suggests a bad connection. As a diagnostic step you can reverse left and right inputs. If the problem moves AMP is OK and the problem is elsewhere. You can also swap speaker connections. If the problem moves to the other speaker, the problem is not the speaker or speaker wiring.
