Hi Klaus:

That seems like a great idea... but with the wrong card. Even though you are intercepting the I2S signal before the card's DACs and using your own, you are still subject to what the Audigy 2NX drivers are doing.

It is not clear whether or not using ASIO4ALL with this card successfully prevents resampling everything to 48kHz when playing back RBCD - and many say it does NOT. Now if you are using SRC (Secret Rabbit Code) or a software upsampler and upsampling to 96khZ then you might be ok. But if you are resampling to 88.2 or 176.4 I think you would be out of luck with the Audigy.

For what it's worth, if all of the I2S lines come out of the same codec, they should be "equal quality". Most consumer /pro-sumer multi-channel soundcards nowadays use a better 2 channel DAC for channels 1/2 and a cheaper, lower quality 6-channel DAC for channels 3 through 8.

If I was going to go through the trouble of pulling I2S lines off of a soundcard codec, it would be an ASIO compliant Envy 24HT based card.

Cheers,
Presto
