This updates Luigi's sound code to the basic code in snd971023... 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.
