Sonos ARC using appleTV 4K and RCA TV
I'm having problems regarding maintaining Sonos Arc soundbar as my preferred source for sound. For example, whenever I switch from streaming one show to the next, despite Sonos Arc being used as my sound source, I've noticed it always switches back to using the regular TV speakers as the sound output. It's very frustrating having to constantly go back to appleTV settings to switch my audio output preferences to Sonos Arc constantly. My TV speakers are the default setting for sound output in appleTV and I don't see any way to change this default. I spend my time having to keep making sound output changes in appleTV settings. This happens when I change from program to program or if I pause and restart the same program...sound always defaults to TV speakers. Any help would be appreciated. Yes, my soundbar is plugged into my TV's HMDI-Arc port. AppleTV is plugged into the TV. Why can't I make the soundbar my default?
