.SH "DESCRIPTION"
.PP
Performs some of the preparations necessary to begin
using a PCM channel.
.PP
Currently the preparations include allocating the
scatter-gather DMA table and buffers,
and passing the
address of the DMA table to the hardware.
.PP
Note that special care is taken when passing the
DMA table address to hardware, because it was found
during driver development that the hardware did not
always ``take'' the address.
