amixer: Mixer attach default error: No such device
 

I have Fedora Core 2. I am unable to reproduce and/or use sound card.
In my /etc/modules.conf I read:

alias sound-slot-0 emu10k1
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :

and I stem that sound courd is available into the kernel.
But I alway get the error:

amixer: Mixer attach default error: No such device

Any ideas?
