Grub2 beep, have an useful solution

[Hammer Attila]

Hy List,

I would like insert one beep character with grub2 first menu item 
(Ctrl+g character, the bell character).
This is not problem, but if the grub2 menus present my display, the 
speaker does'nt play a beep noise. Prewious grub boot manager this is 
works absolute fine.
Or this audio help impossible doing with grub2?
This is useful me my notebook, because difficult hear when present the 
grub2 boot menu with my display.
