ok im about at the end of my rope. ive been working on this problem with my sound card for more than a month now and im gonna freak out.i keep telling myself to just go use slack but i cant talk myself into it so here we go one more time.
needless to say, it dont work! it is a soundblaster audigy 2 (emu10k1) i think all the alsa stuff is right but the card isnt getting an irq. maby someone has some ideas.

# Alsa 0.9.X kernel modules' configuration file.
# $Header: /var/cvsroot/gentoo-x86/media-sound/alsa-utils/files/alsa-modules.co$
# ALSA portion
# OSS/Free portion

## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.

## ALSA portion

Enabling OSS emulation is usually a good idea, it makes older applications work. And it doesn't hurt, since ALSA-aware apps should still use ALSA.
Try this: (taken from alsa-project homepage)
| Code: | # ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-emu10k1
# module options should go here
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss |
Also, make sure the module is loaded:
| Code: | | modprobe snd-emu10k1 |
You can put this module in your /etc/modules.autoload.d/kernel-$VER file if you want it to be loaded automatically at boot time. |

i tried the config from the alsa page that you suuggested but it doesnt seem to help. i really am not convinced that the problem is actualy alsa as if you look you can see
| Code: | # lsmod
Module Size Used by
snd_emu10k1 96644 0
snd_rawmidi 19584 1 snd_emu10k1
snd_ac97_codec 74496 1 snd_emu10k1
snd_pcm 82180 2 snd_emu10k1,snd_ac97_codec
snd_timer 22788 2 snd_emu10k1,snd_pcm
snd_page_alloc 8708 2 snd_emu10k1,snd_pcm
snd_util_mem 4480 1 snd_emu10k1
snd_hwdep 8096 1 snd_emu10k1
nvidia 3918588 12

the mod is loaded ( i did this by hand. #modprobe snd-emu10k1), but
# cat /proc/interrupts

there is no irq for the card. #cat /proc/pci confirms this.
really untill just over a month ago i thought that an irq was required for a module to load. |
