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)

You are trying configure legacy cards. Don't try that (select only detected
PnP card in alsaconf). The option opl3sa2 line with manual resources
should NOT be present in the generated configuration. Select only detected
card (and try to remove the whole ALSACONF block from modprobe.conf).

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.
