Well, if the data is a valid encoded DTS stream then the receiver will detect it as such and will perform the surround sound decoding.
How? You said there were no markers left to detect the stream was DTS. Or am I misunderstanding that?

Actually quite many have. You don't NEED to even have bitperfect as such. The audigy/live cards can also output bitperfect dts and dd with the right software (windvd/powerdvd) and they aren't bitperfect.

You didn't read the test, we are evaluating the digital output of the card, not the analog.

I can't seem to get it to work on my X-Fi. I'm running around 50feet of wire to get the hookup to my reciever, but it keeps saying "Dec Error" on my reciever. It plays regular music just fine in "PCM 44.1" mode though.


I'll keep trying away, neither KS or ASIO has worked on my X-Fi via foobar (acm, bit-matched, all that garbage).



When I play in WMP, I get loud hissing noise. W/ ASIO or KS in foobar2000, the X-Fi must be getting damned close enough for my Reciever to realize it's an encoded stream. I'm going to run a shorter cable somehow, I'm wondering if there's anyway too much interference is in the cable run.

Well I ripped my reciever out, brought it right next to my comp, and plugged it in with a 2ft cable. Wallah!!! DTS/DD decoded brilliantly (though I cant hear the file because I don't have it hooked up to anything).


X-Fi (acm bit-matched) + foobar2000 (CreativeASIO) = 100% bit perfect



Edit:

After furthur analysis, I don't think it was the cable length at all. For some reason, my "SACD/CD" digital input on my reciever won't decode the signals. However, my DVD input will. I believe something is fishy with my reciever. Being that it's a fairly basic entry level reciever, I wouldn't put anything past it right now.

I don't think it's that big of an issue IMO. There are other parts related to quality playback than just being bit perfect. Most people's computer systems/transports are not exactly the best quality.

It can't. It can only decode PCM.

Oh come on, of course I'm talking about digital.

Ever heard of spdif passthrough? Live/Audigy cards support it and using it you can get dts or dd signal to your receiver. This is very simple stuff and it's been used for years. You've never heard about people using live/audigy cards to get a dolby digital signal to a receiver? It's so common it's not even funny.

Audigys specs even have "Dolby Digital 5.1 Pass-through (with Dolby Digital-capable softDVD player & DTS pass-through (with DTS-capable softDVD player)"

You can get spdif passthrough from almost every consumer card.

Ofcourse you need a program that knows how to send the signal. Funnily the emu 0404 isn't capable of spdif passthrough even though it doesn't resample and the audigies do.

I thought SACD/CD was always PCM and DVD could be PCM or DTS. Maybe thats why its that way...

It could be, but I was under the impression they were just naming the digital inputs different names. Instead of Coax 1, Coax 2, Optical 1, Optical 2, my reciever has them named "DVD" "SACD/CD" "MD" etc etc.

I just tried this by taking the reciever from our den and sitting it next to my computer. I was also able to get both the DTS and DD files to play perfectly. You can see my setup in my sig.

And to whoever asked about the dac-ah and DTS... it didnt work.
