Ok, I just finished retesting my Auzentech HDA Digital X-Mystique.
Movie: Lord of the Rings: The Fellowship of the Ring
DVD player: Power DVD 5.0, set for SPDIF out (I decided to eliminate Nero Show Time 2 from the equation as well to see if the results would be the same)
Setting for 24/96 Khz SPDIF PCM to the receiver in the Auzentech driver, I get sound unlike what I was able to extract out of the X-Fi in movies. It was immersive, bright, and loud as hell. I wanted to keep watching the movie.
I then set the driver for Dolby Digital Live 5.1 encoding to the receiver and I get a movie experience yet another notch above what it was doing in raw passthrough. I mean:
In the opening battle scene, the following occurs:
1. With the X-Fi, I can barely hear the arrows fly past the elf's head on the line during the charge. I cannot hear the "big bad guy" swinging his bludgeon during the end of the scene when dozens of soldiers are being flung around. I cannot hear the crackle of the cut off fingers from the "big bad guy" after they hit the ground with the glowing ring.
2. With raw PCM output to the receiver, I can now hear the arrows clearly as they fire. I can hear the "big bad guy" swinging his bludgeon and the air displacing around it when swung. I hear the crackling of the cut off fingers.
3. With DD Live 5.1 encoding to the receiver set in the Auzentech driver, I can now not only hear the arrows fly by the elf's head, but I can hear the air that is displaced by the arrows. The sound is more immersive and even "brighter". I can hear the crackling noises *very distinctively and individually* after the "big bad guy" has his fingers cut off.
Just to make sure I was not unintentionally biasing my results because I had started paying more attention with the DD Live 5.1, or had somehow wanted to hear things that were not there, I listened to the scene in both modes several times. They are VERY CLOSE to each other, but the DD Live 5.1 encoding mode is definitely adding more clarity. I know by all rights it should not, but it DOES. I cannot explain it.
So, now I am going to revise what I said. The Auzentech card STOMPS the X-Fi when using EITHER 24/96 PCM output OR when using DD Live 5.1 encoded output via TOSLINK to my decoder when in contrast the X-Fi is outputting analog via the Creative software decoder.
The difference is so shocking that I am now having a hard time deciding whether I even want to put that X-Fi back in, but *sigh* probably will because I game more on my PC than I watch movies and in that mode, the Auzentech does not hold much of a candle to the X-Fi. I wish I did not have to make these kinds of choices!
Bleh, it seems you are still molesting the stream. 24/96 PCM implies downsamping to two channel (possibly mock surround) and also resampling the frequency from the original 48 KHz. That would explain why it is different than S/PDIF pass-through from the X-Fi. The reduced dynamic range would render some effects louder on the PC speaker kit.
