DVD rom digital out connector and AV receiver

I have a sony str-de475 AV receiver. May I connect my NEC 5800A DVD ROM digital out connector to AV receiver digital coaxial input? And what cable must I use? If not, what soundcard must I buy with digital coaxial output? Would the Soundblaster live 5.1. OEM be OK?

As for connecting the drive's output directly to the receiver, I have no idea. Never heard of anyone doing that. I have heard that the digital ouput of drives is pretty bad though when connected directly into the soundcard due to excessive jitter. Passing the sound over the PCI buss instead allows it to be reclocked by the soundcard which results in better sound.

I would not get the SB Live card for two reasons. First, it has (or had, I don't know if they fixed it) a problem with the output voltage being too strong for some receivers to handle. It could burn out the digital-in section or just work sporatically. There was an add-on card people were buying to fix it.

The second reason is that the SB Live cards resample all audio to 48KHz, even CD audio that starts as 44.1KHz. The resampling messes up the sound. You should find a card that does not resample like the SB cards do.

you might be right X, but I've used my SB live for digital out with no probs. it's dirt cheap too...I saw one with d/o for $25 at a computer show. it sounded fine to me.

It's the difference between fine, and really good. Some people care, some don't. I know I stuck a new ($180) soundcard in my computer and went analog out to my receiver and I've never heard music sound so good on my system. I then did some research into why the SB cards only sound "fine" and was horrified to find out what they do to the music, particularly on the analog out.

But even without going analog out, the resampling of the digital is still serious. However you may not care if you haven't heard it otherwise. And I would be very careful about the voltage problem and at least find out if it still exists.

I'm liking the nForce audio on my system. Too bad you need a new mobo to get it.
