As has previously been mentioned and detailed you can manually disable the pc speaker if you desire:
To get rid of most of the "alerts" (for instance in the terminal): System - Preferences - Sound - Sounds, then uncheck "Play alert sound" ==> This won't however stop the system beeping on shutdown To get rid of the shutdown beep (and perhaps making that last step redundent) you should blacklist the pc speaker: In a terminal type "gksu gedit /etc/modprobe.d/blacklist.conf" =>This will open gedit, go to the last line in the file. Type "blacklist pcspkr" without quotes onto a blank line at the end of this file and then save and close gedit. This has all been said further up this report. -- system beep in jaunty is the most annoying sound known to man https://bugs.launchpad.net/bugs/331589 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
