After just a touch of hacking, I finally got my sound card to work. The
required work was to #define JAZZ_DMA16 in sound_config.h, per the SB
routine:
#ifndef JAZZ_DMA16
#define JAZZ_DMA16 5
#endif
I also found that I needed to edit the Makefile for my kernel (in the
kernel compile directory) and add "-DJAZZ16" to the IDENT line. For some
reason, #options JAZZ16 produced a syntax error when interpreted by
config(8). At this point, I had a working kernel, and a kernel that
finally supported 16-bit sound for my sound card. Yay! But all was not
hunky-dory.
It seems that for whatever reason, the kernel doesn't want to let go of
the DMA channel.

Sequencer busy
isa_dma_acquire: channel 5 already in use
I used xdoom (from the 2.2.5-RELEASE package) to test the card. Though
it hosed because of color differences, it did run setup the card
correctly. I have no doubt that the problem lies in the code, but I am
not a professional programmer by any means.
/usr/src/sys/i386/isa/sound/sb_dsp.c:
static void
sb_dsp_close (int dev)
{
#ifdef JAZZ16
/* Release 16 bit dma channel
*/
if (Jazz16_detected)
RELEASE_DMA_CHN (dma16);
#endif
DMAbuf_close_dma (dev);
sb_free_irq ();
dsp_cleanup ();
dsp_speaker (OFF);
sb_dsp_busy = 0;
sb_dsp_highspeed = 0;
open_mode = 0;
}
I have checked all #include files and found no mention of
RELEASE_DMA_CHN. In this file there is one other reference to
RELEASE_DMA_CHN, but it is in a function. I would like to ammend this
problem, as this sound card sounds much better than the OPTi-931 it
replaced. Rebooting after one "peep" isn't fun.
