Sound Blaster Audigy LS problem

Dear @hackers,
	i recently bought a soundblaster audigy ls card hoping that it
would "just work" with freebsd, but sadly this is not the case.  at boot,
i see that we recognize that there is a sound card, but that's not adequate.
pciconf -l -v:

none@pci2:7:0:      class=0x040100 card=0x10021102 chip=0x00071102 rev=0x00 hdr=0x00
    vendor   = 'Creative Labs'
    class    = multimedia
    subclass = audio

/sys/dev/sound/pci/emu10k1.c defines the following:

#define EMU10K1_PCI_ID  0x00021102
#define EMU10K2_PCI_ID  0x00041102

from this, i've concluded that either a) this card has an "audigy-compatible"
chipset and the freebsd driver just doesn't recognize it, b) this card has an
audigy-compatible chipset and the freebsd driver not only doesn't recognize it,
biut it might even be slightly different, or c) this "audigy ls" card really
isn't that similar at all to other audigy cards.  so, i tried just changing the
PCI_ID defines above to match my card's id, but writes to the device through
mpg123 and xmms give me:
	 pcm0:play:0: play interrupt timeout, channel dead

so the question afer all of this is: has anyone been able to push sound out of
an audigy ls card?  does anyone know what the chipset is (emu10k1, emu10k2...)?
would it be trivial for me to hack emu10k1 into compatibility?

thank you in advance.
-Anthony.

P.P.S. also, someone may want to look at sys/dev/sound/pcm/channel.c (lines 279-282):

timeout = (hz * sndbuf_getblksz(bs)) / (sndbuf_getspd(bs) * sndbuf_getbps(bs));
if (timeout < 1)
	timeout = 1;
timeout = 1;

seems like overkill...

Anthony,

Audigy is not supported in -CURRENT kernel, but there are some patches
to make it work under FreeBSD. I know about five of them:=20

5) http://chibis.persons.gfk.ru/audigy/alexander/audigy_pack.tgz old
patches for 4.x and early 5.0 kernels by Alexander Kurilovich=20

It only knows about PCI IDs. In-kernel driver cannot initialize and
control Audigy cards.

Well, it appears from your page that this driver will not work on
5.1-RELEASE (as stated from i guess 2003-10-19).  I tried building your
driver (on 5.1-RELEASE-p10), and it seemed that i just needed to add

#define PCIR_BARS 0x10
#define PCIR_BAR(x)(PCIR_BARS + (x) * 4)

and also strip (yes, bad) some arguments from busdma_tag_create() to=20
successfully build.  are these differences (addition of PCIR_BAR and=20
PCI_BARS macros and altered prototype of busdma_tag_create()) ones that
we can expect to be moving *towards* in -CURRENT, or are they ones we=20
have moved away from with -RELEASE?

also, do you think that by just redefining the PCI id to match my card's
PCI id for EMU10K2 would fix my problem if the lockfunc and lockarg
were returned back to to busdma_tag_create() (assuming i moved to
-CURRENT where I expect they currently reside)?  do you perhaps know
if the audigy ls card uses an audigy 2 chipset?  after much searching
i could not find any datasheet-style information on the audigy ls
beyond the usual frequency and decibel measurements on creative's
specification link on the product page for this card.

thank you very much for your response.
-Anthony.
