Hi all...
Just had to say somthing about this since im sooo supprised that it worked out first time.
Ive managed to add 3 SPDIF optical outputs to my Revo7.1 card by tapping the AKM4355 I2S lines (the AKM4355 had to be removed though).
I could have added 4 SPDIF outs, but i wanted to keep the original front outs for headphone/misc use.
This will be used for the brutefir active xover + room-eq stuff in my linux box.
Next ill be building a new 6 channel DAC with rectified bridged gainclone amp outputs.
Ive taken some photos of the card:

If anyone wants to do somthing similar, let me know and ill put the schematics/pcb diagrams up.

And people call me crazy for changing a couple of OP-amps on my Revo... 
This is really cool. I might be interested in doing something similar on my Revo in the future. But I would probably try to use balanced twisted pair as outputs which connects to some DIY DAC:s close to the rest of of my stereo.
It seems from your pictures that the original DAC is fed with data from three separate wires, one for each stereo pair. Is this correct?
This together with the thread 'PC-music player' really opens up for interesting uses of the PC. Thanks for sharing this.

Some good program for a music playing linux box. .DS
