No, there isn't a digital audio output unfortunately. It would be easy to add, but the cost of the parts to do it would raise the price by at least $5 or more in the end result...
We want to keep the price as low as possible, yet also keep the quality of the cable high, so coaxial/optical audio wasn't considered due to the fact that it would raise the price in both production and resale.
But as far as changing the BIOS in your girlfriend's XBOX... that is fairly easy. If you would like, you are more than welcome to PM me and I can build a custom NKPatcher w/VGA output for your softmod.
