Thinking of using an M-Audio card with Virtual Audio Cable to
convert surround sound to PCM spdif.
The idea is to use something like the Audiophile 2496 to get an
analog 4 channel output. Feed this into the 4 inputs, sample at
24/96 and use Virtual Cable to route one pair of signals to the
M-Audio spdif o/p, and the other to the mobo soundchip (Realtek)
spdif o/p. Any opinions?
Anyone try anything like this?
I also need an end-to-end of better than 105dB s/n
Would help to explain what you are trying to acheive and why. Are
you trying to monitor on SPDIF powered spekers, or make an SPDIF
security copy recording while recording into a DAW, or something ?

I want to encode both front and rear speakers digitally with PCM.
In other words, to decode ac3/dts and pump it out as PCM streams to
active speakers that accept PCM input.
In realtime presumably ?
Yes.
What I really want is ac3/dts and whatever (BluRay), decoded into PCM
channels.
Free of all restrictions.
But nobody does that in a card, and I strongly suspect that the licenses
for those technologies specifically preclude doing so.
So I'm looking for some good DAC/ADC combo to do it for me.
