I have an Arc, One SLs and a Sub Mini connected to my Sony X95J through eARC and an AppleTV 4K. I keep encountering a problem where my Arc gets an HDMI error and my TV will only use the TV speakers and the Sonos app just stalls when I try and switch the audio to the TV (it says an error happened but no code). The issue is immediately fixed when I unplug the HDMI and plug it back in.
From my initial observation it appears to happen mostly (only?) after I’m airplaying to the Sonos system and then try to turn on the TV to watch something.
I do use my AppleTV remote as my primary remote that powers on the TV and starts to the last used input.
I’ve spent hours googling this issue and can’t find much about it. Not sure if it’s the Sonos or my TV.
