We have had an Arc SL for several months. Once it got warmer, and our central AC unit started kicking on, we noticed that the sound would cut out any time the AC came on. Facts from testing:
- source doesn’t matter; TV, appleTV, AirPlay from phones, even if that’s all off and Sonos Radio is playing. If the AC kicks on, the if the TV is on we see the volume drop to 0. Wait 10-15 seconds, and we can turn it back up. If airplay, the audio stops and it looks like it’s disconnected from the source. If Sonos radio, the song just stops and volume has dropped.
- We thought it might be a signal from the central AC (ie wireless signal/interference from the thermostat), but we had the whole unit and thermostat replaced 3 days ago (yay for AC breaking in the middle of the summer) and it’s still happening, even with the new old-school wired thermostat.
- I’ve connected the Sonos power to an external battery, and it happens with that, too (ie isn’t subject to power surge from the AC).
thoughts?
