I have a Sonos Arc paired with a gen 3 sub and almost since the day I bought (2 months ago) it the sound randomly cuts in and out. Sound on for 1 sec, off for 2. The only way I've found to resolve this is powering off the Arc and back on. There's no common them I can pinpoint as to why or when this happens. It's connect via e-arc to a 2020 Samsung Q90t. I've run the diagnostics report 1811475585. Please help me fix this once and for all.
