Intermittent Sound using Apple TV and Samsung 4K TV
I recently upgraded my TV from a LG B7 oled to a Samsung QLED QN90A. I am using the DirecTV Stream app on my Apple TV 4K (2nd generation) to play live TV. DirecTV Stream worked fine on my old LG tv. On the new Samsung QN90A I am having issues where there is no sound/audio when switching between channels. Sometimes the sound will play and sometimes the sound will not play. This is while watching live TV. I do not have the Apple TV hooked up to a HDMI 2.1 port it is hooked up to a regular old HDMI 2.0 port using a standard 4K 18 Gbps cable. Basically my issue is when I launch the DirecTV Stream app on my Apple TV there is about a 50/50 chance of there being audio or no audio. The video shows fine there is just sometimes no audio. Switching between channels also has it's issues sometimes there is perfect audio when switching to a new channel and sometimes there is absolutely no audio at all when on a new channel. I have tried updating the Samsung TV OS software and have also tried restarting the Apple TV itself through the menu. Both of those didn't work. I don't really want to switch providers to another service because DirecTV Stream app is one of the only ones with the unique channels I sometimes watch. Any ideas or help with this is appreciated. I am using the default TV speakers for audio no extras.
