I then plug in the red/white analog RCA's, while the coaxial is still connected, and sound comes out. It sounds good, as though it's running entirely the digital route... but why must these analogs be plugged in as well? Or is the sound I hear likely just the analogs?

Any help would be appreciated... thanks!

NOTE: my xbox + DVD player are connected via optical digital, and they do not need any analog inputs to get sound... Thanks
If your receiver is like mine in this respect, you have to not only tell it that there is digital signal is coming from this component, you have to choose between analog and digital. You may have to set it separately for EVERY component.
