This version of the emuproc.c file goes with the alsa-kernel/alsa-driver tree.
It makes it possible to register dump some as yet undocumented registers of
the P16V or P17 chip. The chip that is used to 96Khz 24bit audio output on the
Audigy2
The registers with 0x30303030 in them are volume control registers.
0x30 = 0 dB
0x00 = +X dB (Exact amount to gain not known)
0xff = -X dB (The most attenuation possible)

Register 0x60 is the Recording Source register.

I have no idea what the other registers do yet.
