My setup is a Sony 900H and Sonos Arc connected via HDMI. Everything was working just fine until recently when I noticed any audio source other than 2.0 would cause the Arc to stutter (sound cuts in and out). It’s happening with any native app including Netflix, Prime, HBO Max, etc. I performed a factory reset on the Arc which solved the problem for about 36 hours and now it’s happening again. If I change the audio option in the streaming app to anything but Atmos or 5.1, it will. It stutter. Obviously that’s not why I spent $800 on the Arc. I need it to play the highest quality audio an not just 2.0. Any help appreciated.
