Salut,

After calling up modprobe snd-sb16 the /proc/asound directory exists.

Yeah, I compiled the kernel 2.0.36 with /proc file system support, but
without sound support myself. 
After modprobe snd-sb16 the output of cat /proc/ioports includes the 
following lines :

0000-001f : dma1
...
00c0-00df : dma2
...
0330-0331 : Sound Blaster 16 - MPU-401
...
0220-022f : Sound Blaster 16
...
Looks great?

Into a different kernel, which I do not boot when I try to use the
alsa-sound-drivers. OSS/Free works, but unfortunately not the
alsa-sound-drivers.

There is no sound.o modules within /lib/modules/2.0.36/misc/ !

Maybe I put the wrong lines into /etc/conf.modules: 


# Soundcard 
alias char-major-14 snd
#alias snd-minor-oss-0 snd-mixer
#alias snd-minor-oss-3 snd-pcm1-oss
#alias snd-minor-oss-4 snd-pcm1-oss
#alias snd-minor-oss-5 snd-pcm1-oss
#alias snd-minor-oss-12 snd-pcm1-oss
alias snd-card-1 snd-sb16 snd_cards_limit=1
options snd-sb16 snd_index=1 snd_port=0x220 snd_irq=5 snd_dma8=1
snd_dma16=5 snd_mpu_port=0x330

I do not the commented lines do, but when they are uncommented the
alsa-driver doesn't work either. 

The output of amixer :

That means no devices are muted. 
Any ideas what's wrong?
