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, I don't have a /etc/isapnp.conf file and I don't know how to write
one. pnpdump doesn't find anything, anyway. The only interesting thing
that it prints is:

# Trying port address 02f3
REALTIME operation timeout exceeded - Switching to normal scheduling
nanosleep failed: Interrupted system call
# Trying port address 0313

it ends with:

# No boards found

So, I don't think that isapnp would work, anyway, even if I did know how
to write a config file for it (which, IMO, seems completely backwards from
what PnP means!)

Maybe there's a newer version than I have? All I can find is that 1.26,
released in 2001 (!), is the latest version.

This non-working state could have something to do with the related bug
0001296 at the top of this page: isapnp is incompatible with pnpbios and
used the wrong ID's

Also, I've always had to manually configure this card (except in Windows
XP, which might do that automatically) and any isapnp options have always
had to be turned off. So, isapnp has never worked with any of the
available opl3sa2 drivers, OSS or ALSA.

Thanks.

ahaning:

Appeartly, it's another bug than originally reported. The original
reporter uses the ISAPnP configuration.

What does command 'modinfo -p snd-opl3sa2' show on your system?
