PS3 Bitstream question.

[BrutalDawg]

Currently my set up is

PS3 Slim -> HDMI -> AVR -> HDMI -> TV

AVR -> Speaker Cables -> 2 Floorstanding Speakers.

In the audio settings of the PS3 I currently have set to automatic which checks EVERYTHING, and I noticed my receiver during movies display the 5.1 digital diagram but only has my Left and Right channel squared (showing it's using it). But when I uncheck all the 5.1 / 7.1 Linear PCM options etc in the PS3, it now only shows the Left and Right channel squared without the rest of the 5.1 digital diagram.

I heard both and I think they sound the same, but just to make sure does it change anything to my audio when i play LinearPCM/DolbyHD/DTS-HD MA tracks?

And would it be okay to leave everything checked even though I only have a 2 channel setup, I shouldnt be losing any audio should I?
