You are missing a receiver in the equation to process the digital signals. Both the DVD player and TV are going to be digital outputs.

Generally, this is the way sound is hooked up from HDTVs:

You should run the optical cable from the cable box directly into a receiver which in turn sends the sound to the speakers.

You should also run the optical cable from the DVD player into a receiver, again, which sends the sound to the speakers.

As far as I know, without a receiver, there is no way to run sound into external speakers. Some tv's allow you to run sound out an optical "out" jack on the tv to a receiver, but you will get only pcm 2.0 sound.

If you want surround you'll have to do the two connections above.

I'm not sure that helps, but if not, post back.

I not sure about your display but many optical outputs on HDTV's are for the ATSC/QAM tuner to output digital audio. This is not always the case. Are you using either of these tuners?

Your DVD player will not output digital sound directly to your speakers. You need a SS receiver that decodes the DD or DTS out to your 5.1 speakers. I doubt your computer speakers have that built in. The PC sound card did that for them.

The z-680 should be able to take both an optical and a digital coax...

I would run the optical cable from the cable box (as Clearday mentioned) to the control center on the Z-680. For sound from a DVD player, use a digital coax cable to route sound from the DVD player to the control center on the Z-680...bam you have digital sound.

hey i was searching google for a similar question and found this. i do have the z-5500's and i just bought an hdtv. i have a couple questions on hookin this thing up:

1. i read about buying a cable for the digital optical slot. now that cable hooks up from your control pod to the tv correct? now what about the wires that go to the sound card on the pc? dumb question but those arent needed for anything right?

2. i noticed that theres a slot on the back of my tv that says "Subwoofer". it looks like the coax slot on the back of my control pod for my speakers. i shouldnt have to use that right? the coax slots are just for gaming consoles / dvd players?

thnx
