GRUB boot tone on Fedora

[Linux for blind general discussion]

Hi list,


I want to try Fedora on my laptop. So far I really like the experience 
from installation and all.

-- Next I want to add some minor tweak which I like from Debian based 
system which is boot tone.

I try adding "play x y z" to /boot/grub2/grub.cfg but nothing happened.

I hope someone can throw some suggestions. Any help is greatly appreciated.

Btw, it's an UEFI system.

Regards
