The Audigy2 has lots of registers for the emu10k2 chip.
These are accessed by programming
#define PTR 0x00 /* Indexed register set pointer register */
/* NOTE: The CHANNELNUM and ADDRESS words can */
/* be modified independently of each other. */
#define DATA 0x04 /* Indexed register set data register */Basically, one writes the register address to PTR, and then read or write to DATA.
On the Audigy2 there is a similar setup for 0x20 and 0x24. I suspect that this is used to program the p16v chip.
Had anyone looked into those registers, and tried to guess what they do ?
I might give it a go, once I finish the Audigy LS driver.
Cheers James
