When to a "computer show" today. Kept the above in mind. Bought a 
YMF719 card for a whopping $14 plus 8% sales tax to put my AOpen AW37 
our of FreeBSD's misery. Shopped until I found a card with a chip that 
specifically said, "Yamaha YMF719" on it.

Also found new-in-box Kingston 32M 60ns parity 72-pin memory for $30 
each. Now I'm stuffed at 128MB! Also used 4MB Matrox Mill II card for 
$45.

Brand was "Axra". CD includes some Windows utilities from Yamaha. One 
demands a serial number and I can't find a serial number on the package 
that it likes.

It works better than the AW37 not-Pro. But it needs a squelch. Plugged
into my AR Powered Partners FreeBSD plays continuous static. Tried the
card under NT 4.0 first, which apparently turns the card off when not
actually intending to make noise. Don't think this card is up to the
audiophile qualities of the AOpen/Crystal Semiconductor card. Other
statements about 34dB S/N ratios on some cards bear a new level of
truth.

Without telling PnP anything special it was detected and appears to work
(cat /usr/local/lib/exmh-2.0.2/drip.au > /dev/audio) But I think the dma
assignment needs manual attention? Shouldn't it be "dma 1:3" as my AW37
said? This is -current as of 2-jan-99.

Probing for PnP devices:
CSN 1 Vendor ID: YMH0020 [0x2000a865] Serial 0xffffffff Comp ID: PNPb02f [0x2fb0
d041]

pcm1 (CS423x/Yamaha <Yamaha SA2> sn 0xffffffff) at 0x530-0x537 irq 5 drq 0 flags
 0x11 on isa
