changes:
o rip the old select from his distribution to prevent extra pollution
o the code now uses audio dma, helps reduce clicks
o improved card support, should work in full duplex on sb16 cards
o add better voxware ioctl support pointed out by Joao Carlos Mendes
Luis <jonny@coppe.ufrj.br>
o remove an unused file that I included for more complete history
o and MANY other changes
I have personally tested this code with a CS4237 based card and an AWE32
(non-PnP). Both cards worked fine in 8bit and 16bit mode.

The codec part of the board is seen as a set of 4 registers mapped
|
|
at the base address for the board (default 0x534). Note that some
|
|
(early) boards implemented 4 additional registers 4 location before
|
|
(usually 0x530) to store configuration information. This is a source
|
|
of confusion in that one never knows what address to specify. The
|
|
(current) convention is to use the old address (0x530) in the kernel
|
|
configuration file and consider MSS registers start four location
|
|
ahead.
