My laptop is an Acer Ferrari 3000. you can see the specs here

I've disabled the beep - found this in linux distributions - fedora section:
You can disable the login beep by adding this to your
/etc/X11/gdm/Init/:0 file
"/usr/X11R6/bin/xset -b" right after the copyright and minus the quotes.
However I still can't configure my sound settings in any way....
