I get 4K and Dolby Vision/Atmos when I plug straight into the TV, but I have everything else plugged into my switch and would like to have everything plugged into that instead of having one device hanging from the TV, and everything else in the switch. Any idea as to what's happening?
Sounds like the switch OR you need the best hdmi cable or something
Does the switch support HDCP 2.2?
Edit: from below it seems it does.
Did you switch cables with one that's known to work like the Xbox?
I am also having this issue. My setup has google tv into the only 4k60 hdmi input on my tv and uses arc to send audio to receiver. Fire stick sends 5.1,. Google tv only stereo. Settings says it sees dolbly digital as an option. Yet only stereo. All apps too.
Is the audio setting set to "Automatic" in the CC audio settings?
In what app/service you are not getting 5.1 audio?
