Sony STR-DG720 send Audio or just Video through HDMI? - audio receiver reviews

I am confused about the Sony STR-DG720. It says it has HDMI switching, but I can not say whether this sends the only recipient, video and audio not. If you can send audio via HDMI, so I can get the uncompressed HD my PS3, but for the life of me I do not understand! Here are some links to the page:
