merve0o0: Haha no prob yea I was watching tv3 I know 3+1 is not HD/5.1.
I think I is likaly to be a problem with my receiver I will double check how things are connected as the apple TV seems to be passing 5.1 via HDMI through the TV. But that's not ment to be possible
Judging from the way my Sony works (and like you I didn't think 5.1 passthrough was possible) I would say there is nothing wrong with your set up.
If the TV is passing thru the Apple TV Audio as 5.1 then the TV settings are fine and you just have to wait until you get a TV3 program that is actually 5.1 to see what happens. Most TV3 stuff is, as someone else said, stereo in a 5.1 wrapper and will only go to the amp as Stereo. Hence your amp says 5.1 and the TV says and is 2.0.
In other words all is working as it should.
