Well, I'm still not getting any further. I pulled the SB Live! card out
and enabled the on-board sound in the BIOS, to see if doing a kldload
snd_driver would recognize *that*. It doesn't.
The on-board sound shows up like this in pciconf -l -v:
none12@pci0:16:1: class=0x040300 card=0x2a3e103c
chip=0x026c10de rev=0xa2 hdr=0x00
vendor = 'NVIDIA Corporation'
class = multimedia
kldload snd_driver followed by cat /dev/sndstat yields:
FreeBSD Audio Driver (newpcm)
Installed devices:
just like before. :(
---------------------------
Information I can glean from looking at the SoundBlaster card:
On the board:
Sound Blaster Live! 24-bit
Model: SB0410
On the chips:
Creative CA0106-DAT LF (c) Creative Tech '02 C0524 KD692
Cirrus Logic CS4382-KQZ WAEXAR0452
WM WM8775SEDS 4AAADOG
Everything else on there seems to be simple resistors, caps, and maybe a
mosfet or three.
Changing emu10k1.c so that the definition of EMU10K1_PCI_ID matches what
pciconf -l -v found gets the module to recognize that there's a card
there, and then it pukes on the ac97 stuff (which confuses me since this
card claims to be ac97 compliant and the Cirrus chips is there ...)
pcm0: <Creative EMU10K1> port 0xcf00-0xcf1f irq 18 at device 10.0 on
pci3
pcm0: AC97 reset timed out.
pcm0: ac97 codec invalid or not present (id == 0)
device_attach: pcm0 attach returned 6
Looking through sound/pcm/ac97.c I can see that the reset() function is
failing, and the id = line in the ac97_initmixer() function isn't
recognizing the chip on the board.
I got a SoundBlaster Live! because it was listed as a known working
piece of hardware. Apparently this is a newer version of the board that
isn't supported yet. Getting it to work is becoming a PITA beyond what
I have the time and willpower to put in right now.
Is there a piece of sound hardware I can just run down to CompUSA and
buy, that I can drop in here and get this thing working with *today*?
