I have a Hisense 65a6g TV connected to a Samsung hwq60t soundbar via HDMI ARC. It works with the Spotify app and various other places but when I open up the YouTube app the sound stops working. When I turn off the soundbar, it switches back to the tv speakers and works but as soon as I turn it back on it goes quiet again. Do you have any idea of how to fix this? I believe this issue applies to my Nintendo Switch connected via the HDMI dock as well.
Is it the ARC port hdcp capable ?
