Anthem AV Help - MRX 1140 (1 Viewer)

[Nupe1911]

All,

Would really appreciate any help you could give. Please see the YouTube link on the sound issue I am having with this the new AnthemAV Mrx 1140. It happens with the following

1). DirecTV - Switching from one channel to another
2). Switching from Xbox series X to DirecTV.

I have requested a new 4k DirecTV box. Any thoughts would be really helpful
