6c1146c0b8 fix the staticy sound issue 
use timer instead of per-channel interrupts

do playback like the linux driver - may fix nmi-with-ecc issue

05a1fdb459 Simplex devices will always report EBUSY on 2nd (and subsequent) 
opens if the reference count is not decremented on close.

Note that this may result in the reference count being corrupted
on full duplex devices (due to mismatching opens/closes), but the
code doesn't use the reference count for anything on full duplex
devices.

3ac1ca3363 1. Increase the size of the DMA buffer. 
2. Offer half duplex with both playback and record on channel 1 or
full duplex with playback always on channel 2 as a compile-time option.

3. 16 bit record output is byte swapped for some dumb reason. Report the _BE
AFMTs for recording.

a7e1150660 Undo some of my own damage. With this patch, it appears that both 
recording and playback now work correctly.

bb7f26c3d9 Fix channel 1 playback the rest of the way. There are a couple of 
hiccups, but playback now proceeds mostly normally using both channel 1
and 2.

19a0702e86 Get playback on channel 1 closer to working. 8 bit samples work. 
16 bit samples have some sort of choppiness, the nature of which
is not completely clear, but it clearly has something to do with
dma buffer synchronization. But at least channel 1 makes noise now.

8eb3acc9be Fix channel 1, sort of. recording now generates IRQs and the output 
appears to be the correct length, but quality of output has not yet
been tested. Also, full duplex audio (that is, playback on channel 1)
does not yet work. Two constants and I am there!

80a8e065eb Reverse the sense of the signed/unsigned formatting bit. 
This dramatically cleans up playback quality, at least with mxaudio.

fb0ef52838 Finally merge newmidi. 
(I had been busy for my own research activity until the last weekend)

Supported devices:

SB Midi Port			(sbc + midi)
SB OPL3				(sbc + midi)
16550 UART			(midi, needs a trick in your hint)
CS461x Midi Port		(csa + midi)

OSS-compatible sequencer	(seq)

Supported playing software:

playmidi			(We definitely need more)

Notes:

/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).

EMU8000(SB AWE) does not sound yet but does get probed so that the OPL3
synth on an AWE card works.

3e0f102e57 With this evil hack the DS1 driver works on our Intel desktop 
motherboards that use YMF740's.  It has a strange subvendor and subdevice
ID and requires a disturbingly long delay after the ac97 codec init.
Cameron hasn't had this driver tested on another 740 yet, so we don't know
if this is a quirk of all 740's, or if its just something about the codec
that Intel used.
