It's known that audigy 2 and audigy 4 upsamples 44.1 kHz to 48 kHz by the native chip. But does it downsample to 48 kHz if you use hi-res audio - DVD-Audio with 24/96 or other hi-res audio? Thanks for information.

i believe that it can, i dont see why not.

By the RMAA results, when 24-bit mode is enabled, there is no resampling effect showing in frequency range (not even in 44.1kHz). Maybe the input signal comes through Philips UDA (24-bit/5-110kHz ADC) when 24-bit resolution is active and otherwise through SigmaTel STAC (18-bit/48kHz (fixed) ADC/DAC).

If you enable any of those hardware effects/processing do you loose the 24-bit path?

System clock The UDA1361TS accommodates master and slave modes. The system devices must provide the system clock regardless of master or slave mode. In the master mode a system clock frequency of 256fs is required. In the slave mode a system frequency of 256, 384, 512 or 768fs is automatically detected (for a system clock of 768fs the sampling frequency must be limited to 55 kHz). The system clock must be locked in frequency to the digital interface input signals.

16-bit :

(w=44.1, g=48, b=96)

24-bit :

(w=44.1, g=48, b=96)

By many reviews for Audigy 2 cards, results got from 24-bit mode are not 'significantly' better (as should be) than 16-bit results so, IMO, Audigy 2 cards are just supporting 24-bit data format rather than being 24-bit cards.

If you have Audigy 4 (non PRO) there, you can test it by your self w/ RMAA and see if it's better than Audigy 2 series cards.

BTW, because of being fixed to 16-bit/48kHz, does the Creative ASIO driver use SigmaTel when set to this mode and UDA whan set to 24-bit/96kHz (newer Audigies does support this 'resolution w/ ASIO too)?

It should not assuming you use the right program for dvd-audio. But you have to disable all of your effects.
