Summary:                    ISA cards (opl3sa2 in particular) are not detected
properly on 2.6 kernels
Description: 
When brute-force detecting my OPL3SA2 card, the IRQ and DMA1/DMA2 settings
are incorrectly detected by alsaconf from alsa-utils. For example, the
default BIOS settings are IRQ=11, DMA1=0, DMA2=1, but alsaconf detects
IRQ=5, DMA1=1, DMA2=0. No matter the BIOS settings, alsaconf always
detects those settings (IRQ=5, DMA1=1, DMA2=0). If I set the BIOS settings
to that, then the card will make sound (after touching the mixer while
playing audio).

According to perex (author of the opl3sa2 driver):

"The alsaconf tries to gather free resources (irq/dma/ports) from the
/proc filesystem. It might be extended to gather this information also
from /sys filesystem."

create_workqueue was called with (name, 0) so I edited out the 0. I don't
know if this is correct, but it seems to allow the build to continue.

I'll edit this note with any later updates.

Update: The compile finished and I was able to run alsaconf. The card
wasn't detected as PnP, so I let alsa bruteforce detect it. It said it was
going to configure the modprobe.conf file, but when it was setting the
mixer settings, it showed an error that then went away when the final
screen was displayed. Trying to run alsamixer produces and error:

# alsamixer

alsamixer: function snd_ctl_open failed for default: No such device
#

Playing a file in mplayer looks like it's playing normally, but I'm not at
the machine so I can't say if it is actually working or not. I'm guessing
it's not working.


Update2: From /etc/modprobe.conf:

options snd-opl3sa2 fm_port=-1 midi_port=-1 port=0x370 wss_port=0x530
isapnp=0 dma1=1 dma2=0 irq=5

dma1 and dma2 are still being incorrectly detected.

Woah!

I think I may have found my problem. I mounted /sys and my card looks like
it was found!

So, so, so sorry.

Updates added here.
