Yeah, it didn't work. Receiver must have told the ATV it was outputting 1080p cause I couldn't get anything higher than that to show up in the resolution options. Oh well. Eff it I give up and will apparently have to wait till I have a 4K TV to get Atmos again from Amazon since they apparently decided to screw over Sony X800 owners who WERE getting Atmos earlier this year on, well, at the time the only content that had it Jack Ryan. I'll probably still continue to use the Amazon app on the Sony player as well just because I'm not going to deal with the ATV app giving me stereo where it should at least give a 5.1 output.[/B]
Did you try that yet?
