We recently set up a Sonos system in our living room. 2 300 Sonos speakers, an Arc, Sub & a Port.
We have an issue when streaming Apple Music from either of our iPhones, vintage 11 & 13, that a sound that I can only describe as an Apple notification sound comes through the Arc. It resembles the stock sound you might get when receiving a text or plugging in your phone to charge. Not heard when the TV is playing or when playing the turntable or CD player. I have gone through the sound settings on my phone and turned off most of them. the sound persists when we stream music. Sonos tech has listened to a capture of this issue and heard the sound but offered no fix as of today. Any insight is appreciated
