Hey Guys, Can someone please listen to the 5.1 test video below? Are the rear channels playing independently or are they being pushed to the front channels?

My test tones from the receiver are going to the right speakers but it doesn't seem like other other HDMI inputs are going 5 channel.

Lots of speakers from many
manufactures...mostly Axiom
