You should be able to add (or uncomment by removing the leading "#") a line like GRUB_INIT_TUNE="480 440 1" in /etc/default/grub followed by running "update-grub" as root (or via sudo). Those numbers can be expanded to play a tune (the first number is the tempo where 60 is a 1-second base, 120 is a half-second base; followed by pairs of frequency-in-hertz and the duration). If you want to get crazy, some folks have done the Mario Brothers tune as the boot beep http://www.commandlinefu.com/commands/view/8275/grub2-set-super-mario-as-startup-tune Hope it gives you hours of fun.

Heim @ UTC (permalink / raw) To: Linux for blind general discussion I use debian, not ubuntu, but I believe the process for getting a beep at the grub boot prompt is the same. There is a file /etc/default/grub with a line at the bottom that is commented out. You uncomment that line and run update-grub. This is all explained in the file itself. You can also make it play a tune. I've included an example line that plays a few notes of "On Wisconsin" This is not entirely trivial in that it makes it very clear when to interrupt the boot process in order to select an operating systems. I always tell my end users to press the down arrow once when they hear "On Wisconsin". # Uncomment this line for a beep at start up #GRUB_INIT_TUNE="480 440 1" # Play "On Wisconsin" at start up GRUB_INIT_TUNE="1000 334 1 334 1 0 1 334 1 0 1 261 1 334 1 0 1 392 2 0 4 On Mar 2, 2013, at 7:53 PM, John J.

I would like to set my grub to play > the first few bars of Beethoven's Ode to Joy. I don't know about the calculation but there are lots of Linux apps for making music files. Reviews of some here. <http://www.makeuseof.com/tag/top-5-free-linux-music-creation-tools-artist-budget/>. I don't know how they are on accessibility. This site seems to be the motherlode for info on all things audio on Linux. <http://linux-sound.org/>. If you navigate down the left frame to " Linux Audio Bundles & Distributions", that's a link taking you to a page with a bunch of apps and audio distros, including at least one that's a live CD and another that's a live DVD. I haven't tried any of the above. Best regards, Paul ^ permalink raw reply [flat|nested] 11+ messages in thread

The frequencies can be calculated by multiplying / dividing the base A4 (440Hz) by the 12th square root of 2 (1.0594630943592953), but it's simpler to just use a table like http://www.phy.mtu.edu/~suits/notefreqs.html Samuel ^ permalink raw reply [flat|nested] 11+ messages in thread

Heim @ UTC (permalink / raw) To: Linux for blind general discussion Yeah, as Samuel said in his response, I looked it up in a table when I figured out how to make it play "On Wisconsin". I'd be interested in copying your grub directive for playing Ode to Joy. When you get that figured out, would you post it here, please? I am always looking for more tunes because I like to have grub play different tunes depending on the boot medium and version of the operating system. If I'm trying to boot from a CD and it plays "On Wisconsin" instead of "Close Encounters", I know it didn't work. Anybody else have interesting ones, let me know. On 3/3/2013 10:46 PM, John J.
