S/PDIF support

It is supported only for 2-channel PCM data, as I know. Non-PCM (like AC3) I/O may not work.

emu10k1 driver in -CURRENT can be modified to allow recording from S/PDIF inputs on Audigy cards (just 2-3 lines in DSP sound routing code). 
You can also try my emu10kx driver that can be set to record up to 44Khz 16bit stereo from any stereo input (including S/PDIF inputs) on Audigy (including coaxial and optical inputs / outputs on LiveDrive). I don't have equipment to test it, but I think that it can work.
