I've started a discussion over at hydrogenaudio about this too but they don't know so I come here.
(http://www.hydrogenaudio.org/index.php?showtopic=11725)

The question is: Is the digital signal path from an application (say 'winamp') to the SPDIF-OUT (on my audigy drive, I have an Audigy 1 Platinum) 'Perfect'? With perfect I mean: when I turn all fancy options off, no DSP, no EAX, no nothing, will the output of my audigy spdif be exactly the same as the signal winamp sends in?

I have read in your FAQ section here: http://kxproject.spb.ru/direct.php?language=en that the -recording- of the audigy usually is at 48000 khz, but is this true for the output path as well? Does the audio resample my 44khz mp3 data TWICE? 44 -> 48 -> 44?

(My original question was: is there any use to buy a mega expensive soundcard when all I want to use is its SPDIF out, directly into my very expensive 44/48Khz DSP-DAC. I don't care if the audigy DAC's are crap or not, I don't use them

And: will installing the KX drivers 'fix' all this?

on top of this from that same FAQ page.. how does this apply to my setup (with kx drivers working now, and with a creative soundblaster live, not audigy)

"Moreover, if the input stream frequency is already 48000, it is still resampled in order to avoid possible synchronization issues."

i am using SSRC resampling on my music to make it 48khz to get into the ASIO outputs... will the creative card resample this again, or are these inputs concerned with SPDIF inputs only from external sources!??

External inputs only...

brief, but that's all I needed to hear. Thank you.

Good in that case I guess I can leave my system as it is. (all set to 44, I dont record much).

On the other hand perhaps I should consider KX afterall since it switches front and rear analog outputs which I still use (rear, that is) for surround... choices choices.

I said this about 48->48 resampling only (jimbobuk asked about exactly this case)... 44->48 resampling is done for all the sources (like FAQ said)...

btw. what kind of equipment your external DAC is?

and...
>Does the audio resample my 44khz mp3 data TWICE? 44 -> 48 -> 44?

why twice? ok 44->48 first, but then no resampling takes place if your DAC can work with 48000Hz right...

There must be some misunderstanding about what you call a 'source' then. (Sorry if Im asking the same question over and over, thanks for being patient with a poor newbie )..

Do you consider "Winamp.exe" a source?

As I said, I don't really care about recording. If the SB CAN just playback 44khz output unresampled, unmodified (with standard drivers or with KX) over SPDIF then I'll be happy (with the Audigy control panel you can set the audigy spdif out at 44khz, which is what I do right now). If the SB is 48000 internally for input AND output paths then I have to reconsider the situation. (I guess set output to 48 until perhaps I buy a new card? Or use KX?)

Professional Studio DSP basically:

Well that was where perhaps I was confused? Yes of course I can set it at 48k so if as you seem to say the Audigy is at 48Khz for all situations, then it would be better to not resample again from 48 -> 44. But your Direct Recording guide (http://kxproject.spb.ru/direct.php?language=en) only mentions recording when it says 'emuxx are fixed at 48000Hz' so I assumed playback was un-resampled.

Bump.

Heh. After 3 years I still have the same question:

- Is there some way to tell the audigy/kxmixer/whatever to just send an exact version of the digital source (winamp?) to the digital out? I do NOT want it to resample!

Or do I have to buy a new soundcard? (suggestions?) All I want is a 'perfect' SPDIF output that will not do anything unneccesary with the digital data winamp produces.

buy a new card...
