I heard there is a simpler way to do it in the command-line but I couldn't remember so, as far as i know... there is another way to beep. You will need a C compiler (gcc), /usr/include/stdio.h and nano. (These are already in Mint 13).
We are going to use the Bell escape code technique, Follow these steps:
1. Open up terminal.
2. Type "nano test.c" and paste this code in to the text editor.
3. Press CTRL+O and Enter and CTRL+X (CTRL = Control Key).
4. Type this in terminal:
If things went well, you should see nothing.
5. Type this in terminal:
Please quote my post whether you hear a beep or not.
Hey, dude. I know what beeped before the OS... It's your BIOS! BIOS = Basic Input Output System.
It runs everytime you boot. Most computers have BIOS. The beeps from BIOS mean something too!
If it beeps weirdly then it means your computer has a problem, etc.
If it beeps like what you hear everyday, your computer is OK.
Also, On some modern laptops. The Internal PC Speaker isn't installed. So, You just can't get it to beep because there is no speaker...
The official X230 manual talks about the usual IBM/Lenovo beep codes that go back more than half way to the dawn of computing. What I don't know is if there is a separate tiny little buzzer tucked away somewhere, or if BIOS has a way of activating the same speakers that an OS later uses for routine sound. Either way, both BIOS at POST (power on self test) time and GRUB at boot time evidently have some way of activating something that vibrates and makes a sound.
What I am trying to figure out is what to call in a script running as root in a Linux environment, that does something similar. Specifically -- since beep(1) appears not to be supported -- I am broadening my question to ask, what would be the usual way to get root to send an audible signal in Linux Mint Mate 13 Maya? Getting such a script to su to a non-root user to run a complex media codec just strikes me as weirdly over-complicated. Is there a simple "normal" way to do this?
