Hi Nigel & Mikkel,

I have downloaded ALSA driver from
ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver/

After googling I found that I am not the only one that experience sound 
problem on ACER TravelMate 6291. I am waiting for FC8 release to solve my 
sound problem (and other problems). I might try to find some way to install 
my newly downloaded ALSA driver (though it seems rather complicated for me). 
Now I am focusing on finishing my Linux & C++ books.

But I am still curious when I tried to run:
#depmod -a                ---->OK
#modprobe -r snd-card-0   --->I got error message (see below)
FATAL: Module snd-hda-intel is in use
#modprobe snd-card-0  ---->OK

What should I do to avoid above error message.

Thanks
yunus
