TX-NR609 Audio Question

Hey there, quick question. I'm running an HDMI cable from my cable box to my receiver, and an HDMI cable from my computer to my receiver.

Is there any way I can play music on iTunes, and watch TV at the same time? Example, if I have people over and we want to watch the baseball game, but listen to music at the same time, is that possible?

I went to a few forums last night (while the site was being updated), and I got mixed answers. I usually trust AVS Forum's opinion the most over anyone else. :P

Don't know how to edit, so hopefully this merges with my original post.

tl;dr: Can I watch video from HDMI 1, and have the audio from HDMI 2? If not through HDMI (which I don't think I can), can I somehow run some RCAs or something?

Bump.

Bumping up again.
