the fact is that it only worked at first boot after installation. I cannot 
now install again
fedora on this computer. Too complicated now. Is there anyway to solve 
this modifying alsa
settings or whatever?
The mixer is ok. all the volumes levels are high noone is mute. I just 
can't figure out what the
problem is. I also tried with another pci sound card and everything was 

Thanks Kevin

my modprobe.conf is now
