I have an Arc, sub and 2 play 1s setup. For a month now the setup was fine. No sound issues at all. No changes made to my network either. Since yesterday my arc keeps dropping out intermittently. For no reason whatsoever.
I have tried wifi and ethernet. Same issue. I have had to turn the arc off and revert to TV speakers
