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)

When I compile all drivers (not just --with-cards=opl3sa2) none of them
work.

I have now enabled kernel and BIOS support for PnP. With
alsa-driver-1.0.9b compiled with --with-cards=opl3sa2, no PnP or PCI cards
are found.

I don't see why I should need drivers other than opl3sa2.

Please, follow my instructions. I have not written to recompile other
drivers. I meant that in alsaconf should be selected the pnp card not
probing of legacy cards.

Also, follow ALL requests from
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=879#5608 and
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=879#5641. If you do
only partial steps, it avoids me to do proper conclusions. I don't have
opl3sa2 system around, so I rely on your input.
