Hi, I am not really sure where this issue lies (TV, Receiver, etc.) but thought I'd start here. So I have an Apple TV connected directly to a Samsung QN90A with eARC sending sound to my Denon AVR-S960H. On the Apple TV, I run Plex. Sometimes (often but not always) I hit PLAY on a show and there is no sound. I stop playback, hit PLAY again and I have sound. Sometimes I have to go through that cycle 2-3 times. I guess it's almost like either (a) the TV is not sending the sound (sometimes) or (b) the receiver is not detecting it (sometimes). Any help is appreciated!
