View Full Version : Ideal PCI/e card for S/PDIF-in DD or DTS decode?

03-28-10, 10:00 AM
Looking for models that are readily purchasable, & with good support in Windows 7.
Solid Linux support would be ideal to, at least for S/PDIF-in.

Ideally it'd be relatively cheap, as this is all I want the card for!
I will re-route it's decoded stream to another card for DAC (where possible).

I already have a dedicated device for DD/DTS decode, it's mainly for experimentation.

These look like they should, not 100% sure about the last two though.
I would prefer brands other than Creative, if people know of others.

Sound Blaster X-Fi Elite Pro

Sound Blaster X-Fi Titanium

Sound Blaster X-Fi Titanium Fatal1ty Pro

Sound Blaster X-Fi Titanium Fatal1ty Champion

Sound Blaster X-Fi XtremeGamer
E-MU 1010 PCIe

What is wrong with your first thread?

The Asus D2X would be your best bet. For non Creative, but Creative will be cheaper for a product that'll perform exactly the same.

Because it deviated to a couple of different topics.
This has one central focus & is less likely to be confusing.

Why? Any thoughts/advice? Thank-you!

I just saw your updated post, thanks for adding your thoughts!

Are sure you're not thinking about S/PDIF-out for the D2X?
I'm sure I've read & others have claimed, that it can't do S/PDIF-in DD/DTS 5.1 decode.

Well I can't say 100% but from the Googling I found peeps were running their consoles in through the D2X and having it decode out to their analogue speakers.

Hmm my googling didn't reveal anything, can you recall what query you tried?

I'm more interested in s/pdif-in decode & then rerouting to DH or similar, but decode and then output to speakers is a good start!

OK. I think I'm getting head around this. It seems only 2 channel sound can be input into most consumer levels cards and re encoded. However it seems this is not what you want, nor most other people.

The input of AC3 to be decoded by the PC/Soundcard and outputted to another source is NOT possible in the way a receiver/amplifier will. HTPCs just cannot act as a decoder for an outside digital source. ::(:

I did find this post

Perhaps it can be implemented. Although I wouldn't hold my breath.

PC's can be used (or used to be; recent cards + proper dvr support is proving to be a PIA) to receive DD/DTS 5.1 via S/PDIF, there is sufficient bandwidth for those formats.

PC's just aren't usable for HD audio, which is 6ch PCM or greater & uses the newer (HD) surround formats: TrueHD & DTS-MA.
These formats require bandwidth too high for S/PDIF, & regardless they're protected by PAP & hence cannot be "received" via HDMI.
So alas they can't be captured for local reprocessing.... :(

This is why I'm only looking at S/PDIF-in decode....

I did find this post

Interesting find...
One usr claims this feature is coming, and the last poster lists a series of cards which he says can already do this!
I will investigate further, thanks!

Thanks for that crainger, you saved me a lot of wasted time!
Might buy you a carton if I'm ever down Coffs Harbour way, assuming you're of age ;)
