Sound card for optical out mixing analog in

[jasperdog]

Hello, in need a sound card for which the digital output, preferably optical, allows the mixing of both analog inputs and internal computer digital inputs like BluRay audio. I also want zero delay (as close as possible) for the A/D conversion.

So, you basically need a Line Input, Optical Input, and Optical Output port?

Based on that, I'd go with the ASUS D2/D2X, the HT Omega Striker, or Auzentech Prelude.
