Must analogs be connected along with Digital Coaxial to get sound? Seems so...

[BoostedA4]

I have the Onkyo HT-S760 home theater system and digital cable. I am running a digital coaxial audio cable from the digital cable box to the receiver. I then make sure the receiver knows that video 1 (TV) is coaxial connected. Sound, however, is nonexistent...

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.

I don't have digital cable so I'm not familiar with its receiver setups. I wonder if it has a audio setup similar to DVD players, letting you choose SPDIF/RAW instead of analog...:confused:

I have to agree with Geoffcin, your receiver should show if it is getting a digital feed or analog (most do) and once you set it, it should show the different kinds of digital feed its getting: Stereo(2.0), Stereo surround(4.0) or 5.1 it will vary from each station and program
