I purchased my Sonos Arc at launch. Everything was great (no issues) until about the last week or two. Suddenly, my Arc emits a periodic chirping sound every hour or so. The sound only lasts for about a second and happens whether the speaker is in use or not. I have done a power cycle on the Arc and checked for updates, but there has not been any change. I was asked by Sonos to record the sound, but it happens unexpectedly and briefly so I have no way of doing so.
The sound is similar to the beep when a smoke detector’s batteries are low (not as loud but similar in tone and pattern). Any insight or solutions?
