I watched some of JW 2 this morning, and I experienced major audio cutouts, to the point that there wasn't any audio for at least 5 minutes, so I stopped it. I was using Dolby Atmos on my Denon, so thinking that might be the cause because I don't have an Atmos setup, I switched audio formats to the next English one, which ridiculously was 2 channel (the receiver converted it to 7.1, but it sounded terrible. There was a 5.1 option in the setup menu, but it was in French.

So...... does Dolby Atmos only work if you have an Atmos setup, or is something not right with my receiver?

The only reasonable argument for owning a gun is to protect yourself from the police.
