Enable in Ubuntu

If you want some scripts to emit beeps, e.g. because you don’t always have your headphones on, you first have to enable the pcspkr module. This is per default disabled in Ubuntu. To enable it again, do the following:

1. open /etc/modprobe.d/blacklist.conf in your favorite editor (using sudo)

2. find these lines:

    # ugly and loud noise, getting on everyone's nerves; this should be done by a
    # nice pulseaudio bing (Ubuntu: #77010)
    blacklist pcspkr
   

3. comment out the last line
4. finally, do a sudo modprobe pcspkr

After that, you can play around with the beep program.
