Beep in shell script not working?
When using the Terminal application in Ubuntu I never seem to hear any alerts. How do I turn these sounds on?
I've tried looking in Edit > Profile Preferences and confirming that "Terminal Bell" is checked (which it is.) I've also checked System > Preferences > Sound and I'm using the default Ubuntu them with the "Alert Volume" cranked. Music and video sound fine.
To simulate a bell I've tried irssi, typing echo -e "\a", hitting tab and backspace but nothing seems to make a sound.
How do I fix this?
