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)

Is there any news on this? I see on LKML that there is a move to remove
"obsolete" OSS drivers from the kernel. This could be fairly disasterous
for people who don't know how to configure their OPL3SA2 card in 2.6
kernels with the ALSA driver, since alsaconf will not detect those cards
correctly on 2.6 kernels.

I was told to file a bug report, which I may do eventually, but I figured
maybe it would be best to keep everything in one place. And since I'd
already posted what I know in this bug, I didn't think it would be worth
writing up another bug report.

Anyway, just wanting to see what may have been done to get OPL3SA2 cards
detected and working well on 2.6 kernels. Thanks.
