Hi Piero

I have an Intel based laptop.
The snd-intel8x0m is the modem driver. Which you will need.
I also tried to disable it when trying to compile the modem drivers, and
it did not work.
The reason which I can't remember can be obtained by unblacklisting the
snd-intel8x0m module from /etc/hotplug/blacklist and running 
rmmod snd-intel8x0m
It will swear at you,

The sound card depends on this module to be loaded or something like
that. 

But in my google searches I also read about some guys who could remove
it and some who could not. That could be based on your sound / modem
hardware or you kernel version.

The best advise I have for you here, is get the latest initscripts, hal
and udev from fedora.us updates and even go for a newer kernel (maybe an
older one if you already have the newest) Then install the latest alsa-
lib and run alsamixer. 
Pay attention that on my sound config (similar to yours) all devices are
muted by default,
You will need Master and PCM turned right up to hear any sounds from a
movie mp3 or system sounds if they are enabled.
Also check which sound system you are using. it should be alsa.

Cheers for now.
