Suggestion for grub beep notification

Suggestion for grub beep notification

Hi guys,

I am using grub to book a dual OS computer. When I start/restart the
computer, I want to be notified by a beep, so I can make the OS selection.
I enabled the beep by uncommenting the line GRUB_INIT_TUNE in
/etc/default/grub but the beep comes up a few seconds before the grub  menu
is displayed. While this is not a big issue, is it possible to change some
configuration so that the beep happens after the start menu is displayed?
It doesn't make much sense to me to have a beep then look at the black
screen for five seconds or more before I can make a selection.
 I use OpenSuse Leap 15.4 in case it matters.

Kind regards,
Nicolae

I've not tried this, but what might get you what you want it to use the
"play" command to create a tone. I think if you put it at the end of
the grub.cfg it'll happen after the menu is displayed.

Hi Glenn, thanks for your answer. I edited /etc/default/grub and appended
to the last line the command
play 60 440 4
When I do update-bootloader, it tells me
+ /usr/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg
/etc/default/grub: line 50: play: command not found

I tried next to use the command: play "60 440 4" but I got the same error.
I also tried moving the command GRUB_INIT_TUNE="480 440 1" to the last line
of the grub script, but the beep comes up about 6 seconds before the menu
is displayed.
