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)

I uploaded new alsaconf script. Hopefully, it will work on your system.

perex:

I copied the attached alsaconf script over my old one and ran it. The
first time, without rebooting, it said it found a OPL3SA2 and would write
the configuration to /etc/modprobe.conf, but either it didn't or it
detected things incorrectly.

After rebooting, it won't even detect the OPL3SA2. "No legacy cards
found."

What version of ALSA and the kernel are you running? If we can try to get
at least similar software, it might be easier to debug these issues. Also,
what kind of OPL3SA2 are you using? I have one in my Gateway Solo 2500 and
I have PNP turned off in the BIOS.

Thanks!
