Summary:                    (snd_)opl3sa2 (isa) doesn't work (fails on playback)
on 2.6.x kernels
Description: 
It doesn't work on all 2.6.x kernel I have tried (current 2.6.10)
alsaconf doesn't detect the card as PnP, and fails to find it with
bruteforce.

When module is loaded by hand it shows no error, but on `aplay samle.wav`
I got
"ALSA /work/install/alsa-driver-1.0.5a/alsa-kernel/core/pcm_lib.c:2172:
playback
write error (DMA or IRQ trouble?"

on boot with 2.4.x kernel, everything magically works (alsaconf, aplay
etc..)

the bug is reported 4 months ago on
http://bugzilla.kernel.org/show_bug.cgi?id=3117
that's why some versions are old (but I had tried alsa-1.0.8 before
reposting this bug here)

Well, with the help of some people on LKML, I've successfully built
module-init-tools 3.2-pre7.

I've installed alsa-utils-1.0.9 with the above patch and installed the
above-attached alsaconf.

When I run alsaconf 1.0.9a, it does not detect my card as a PnP card. It
will brute-force detect the card, however. The dma1, dma2, and irq are
wrong, though.  When I fix them in the modprobe.conf file, I can do
'alsasound restart' and the card appears to be detected. When I go to play
something, I won't get sound until I touch the PCM mixer.

If it would help, I can repost my /sys directory.

Thanks.

Edit: FWIW, here's my modinfo -p snd-opl3sa2

# modinfo -p snd-opl3sa2

Well, I finnaly successed of making sound work.
The only thing that helped was setting BIOS to 'PNP OS = YES'.
This only comes to proove that the kernel is the reason of all problem.
The real question is where to look now.
