FC5 Sound problem after fresh installation !!

[Ameur Mohammed]

Hi all,
I installed FC5 on my Toshiba A60 notebook with no
problem, after the first boot I tested the sound and
did here the test music sound, I loged in GNOME and
check the  volume control and every thing seems to be
fine, after I rebooted the machine I log back in GNOME
I found the little sound Icon muted, and the device is
Modem Speakers !! I tried alsa mixer and it gave me
this : 

alsamixer: function snd_ctl_open failed for default:
No such device

I also updated alsa-utils didnt wok too, I am new to
linux and I dont know why the system changed the
device ! and how can I configure it like it was before
rebooting, I tried Login as root and its the same
problem.

Your help is very appreciated

Many thanks
