Hiya guys. hopefully someone can shed some light on this because
hours of googling has failed to find an answer. I am using OpenBSD
3,4 i386 release. My motherboard has an ICH5 (82801EB) chipset on it,
with a AC97 audio device embedded in it. I believe the driver that
openbsd uses is the "auich" driver. I have 2 machines here, my other
one has an 82801AA chipset in it and the sound works fine there.
heres a snippet from my dmesg:

cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 2
cd1(pciide0:1:1): using PIO mode 4, Ultra-DMA mode 2
"Intel 82801EB/ER SMB" rev 0x02 at pci0 dev 31 function 3 not configured
auich0 at pci0 dev 31 function 5 "Intel 82801EB/ER AC97 Audio" rev 0x02: irq
10, ICH5 AC97
isa0 at pcib0
isadma0 at isa0
pckbc0 at isa0 port 0x60/5

so wheres audio0 at auich0 ?????
the device appears to be detected but not configured?
"man auich" is useless so please dont tell me rtfm! I've done it.
Device uses function 5 which doesnt mention that its "not configured"
so it would work right?!?!?

Has anyone had any luck getting this device to work??

regards, alex.

Can you recompile a kernel with this patch applied, and let us know if
this solves the issue?

Thanks in advance.

i havent built a custom kernel under openbsd yet.. so not sure what needs to
be done. built plenty of them under FreeBSD. Is it anything like the way
its done under freebsd?

being the impatient person I am, i went out and bought an SB live card.
Put this in this afternoon, it works, but rather poorly, the sound
skips/repeats.

I have compiled kde 3 from scratch which is using the OSS. I tried making
the audio buffer as large as allowed, it helped a bit, but if I even open a
terminal window and drag it around the screen, the sound stuffs up. lol

System is a Pentium 4, 2Ghz
1GB Dual Channel DDR 400 RAM
80GB ATA-100 HD
Nvidia Geforce4 MX440 128M

Is the SB Live driver under openbsd broken? surely my system has enough
resources.. dunno what the problem is there..

not having much luck here with sound everything else works though..

anyways.. back to the ICH5, how do I apply the patch?

Pretty close: refer to FAQ 5.4 for details.

I can't say anything without a complete dmesg of your system.

Save the patch to a textfile, tehn
cd /usr/src/sys/dev/pci
patch < the_file_which_contains_the_patch
and recompile a kernel.

FYI: A recent snapshot shows this:

OpenBSD 3.5 (GENERIC) #27: Wed Mar 24 03:03:20 MST 2004
deraadt@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC

ac97: codec features headphone, 20 bit DAC, No 3D Stereo
audio0 at auich0
auich0: measured ac97 link rate at 48002 Hz, will use 48000 Hz

-- Mark

so its been fixed in 3.5?

his hardware is different than yours. works there, but not for you. the
patch to fix your case hasn't been committed because you didn't tell
anybody if it worked. please test it.

no, it's too late for that.
