Got my Arc 2 weeks ago.. after about 2 hours of tv the sound starts distorting, a tick sound every few seconds plus tv sound goes for a fraction of a second.. pause the tv & tick sound continuous… so this must be the Arc not the signal.. I’m using optical as the arc hdmi didn’t work when I set it up, plus the previous speaker was on optical & never had any problems…
I’m really p’d off as I waited a long time for my Arc & Sonos customer service is nonexistent….
Any advise appreciated…
