The other was the internal motherboard sound for all 48khz.My solution was to buy a Revolution 5.1, with a Envy24 chipset that can autoswitch between different digital output rates so that the stream always ended up at the AV reciever in their original form. Works well, I recommend the card.FINALLY. After exhaustive testing with the audio outputs on the Revolution, I now use the analogue outputs going straight into the AV receiver. This allows me to use FFDSHOW to:- upsample to 96,000- remix into 4.1 (I have a phantom centre)- EQ signal (based on testing with AVIA test disk bass patterns, really only for bass config, top end is much harder and hence left alone for now)- delay by 20ms to account for HDTV delayI also use reclock, and this can also resample the audio after all the above processing in order to keep sync, so good to be at a higher rate than the default.So, for all this you'd think the sonic soundstage or whatever audiophiles call it would be ruined. In fact, the difference is great. If you take the total difference over using the AV receiver to decode a raw digital signal, it is something no one could argue with in person.I hope to improve music quality with oversampling in future, although Hwarhmann/Symphy have done some fantastic work lately. I can use the EQ's I worked out in FFDSHOW and use them in a VST EQ plugin. It would be great perhaps to be able to oversample first (just as your stand alone CD player would do) then EQ, then analogue out to the amp.Waffling here, sorry, hope my story is useful.vvvvvv I don't think that driver existed back when I was using that card (2 years ago). Plus I'm now in the analogue domain and the old card had awful DACs compared to the Revo.</blockquote>
