No issues when watching TV.
No issues with the TV off and streaming my itunes playlist from my windows laptop via airplay.
As soon as I stop the music streaming and put TV back on (Samsung QLED 90T), the sound from the Arc is intermittent, it keeps dropping in and out.
I pull the master plug to Arc, TV & Virgin V6 box, put them all back on and then no intermittent sound from Arc while watching TV, issue only repeats if I stream music again as described.
I’ve seen other posts about intermittent sound, but those threads are when watching TV, not after music streaming.
On the Sonos app I noticed TV Autoplay and Group Autoplay are on (although I have no other sonos speakers connected). Just wondered if anyone else had similar situation, if not I will contact Sonos support.
