Apple TV 4K random black screens
So I recently purchased a sonos arc and have it set up on my tv but since the install my Apple TV will just go to a random black screen and lose hdmi signal for about 2-3 seconds then come back on and what ever content I was watching is paused. It also does it when the screensaver is going as well. I have also noticed that every time on my tv when it does this it changes from Dolby audio to stereo audio until I hit play again. My tv audio is set to bitstream and the Apple TV audio format is set to audio. I have tried to change Audio format on Apple TV to both stereo and dolby 5.1 but the issue still persists. I have also tried multiple hdmi cables without success. The Apple TV worked fine with my previous surround set up although that setup was coming out of the tv via an optical cable. Any suggestions on what could be causing this issue and how to fix it?
