I currently have my TV playing through the line in to the left hand speaker in a play 5 stereo pair. I have not been able to successfully troubleshoot the issues I am experiencing with drop out on the right hand speaker. Initially I had the TV playing through a play base, via optical input. I subsequently bought the 2 play 5s and grouped them with the playbase. I then realised that they provided better sound than the play base so the playbase was moved upstairs and I used the line in input on the left play 5. As soon as I did this I experienced intermittent drop out on the right hand speaker. I have connected the lift hand speaker via ethernet cable to see if that fixed the issue. Unsuccessful. I restarted every sonos item in the house, left play 5,right play 5, connect amp, and play base. This appeared to work for a short time but the problem has returned. I have tried allocating specific ip addresses to each item to try to minimise cross over.
Can I submit a diagnostic for some technical support please?
