What modules or kernel options did you compile under ALSA? (Or if you used the alsa-driver package...)
Please show what modules are loaded (/sbin/lsmod) and the contents of your ALSA config file (Probably at /etc/modules.conf.d/alsa).

i have stuff in /dev/sound.. it has mixer, control0 and some other jazz..
lsmod just shows nvidia (for my video card). I compiled sound support directly into the kernel..not as a module. I am configured it to use both Intel drivers.. it was something like Intel (i8xx), SiS 7012, NVidia nForce Audio or AMD 768/811x.
i just got to work so i cant log into it remotly |

You forgot to uncomment a few lines in here:
| Quote: | ## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1 |
You need an alias line that matches your sound card. It's strange that ALSA detects your midi as a separate card. It probably explains why you have so many devices in /dev/sound.

I see. but I am a tad confused about something. I've compiled my sound support directly into my kernel. So any module i put in /etc/modules.d/alsa will not be found .. am I wrong in thinking that this file is used to configure modules?
should i simply just recompile my kernel and use modules for this? When I added snd_intel8x0 to my config it tells me module not found.. but that is my driver that is built into the kernel..
from dmesg

Do you have a strange power saving mode enabled?

I prefer to use modules whenever possible. It frees up some system memory and it makes debugging simpler. It's certainly not required, and it can sometimes lead to new problems. It's up to you if you want to try it.
You need SOME place to have the configuration files for ALSA. There might be another configuration file for ALSA in /etc, in which case, that would work better. If not, you might have to edit the file in /etc/modules.d/, even if it normally wouldn't make sense to do so.
