Setting up a 360 -question about video/audio outputs-

[TRios_Zen]

A boxed 360 should have come with TV out dongle for Non-HDMI TVs (you know, RCA, composite outputs) and that has an optical out for digital sound.

Ask your friend where his is, as I think that is the only way you are going to get it, if your reciever doesn't support HDMI audio.
