Noise when hitting backspace

 Thank you for taking the time to report this issue and helping to make Ubuntu better.

Try changing the system sounds alerts. Go up to the top taskbar and click on

System - Preferences - Sound is very near the end of the long sub-menu

a gui console should appear, click on the "Sounds" tab (i think the first tab is "Devices" - personally i switch all of these off and also do the one in the System-administrator-login aswell. Good luck hunting for the backspace alert :)

If you are still having trouble with this then please post it as a new question. Only the most recent questions tend to get looked at so posting/re-posting a question just before america arrives online after work/school gives the best chance of getting a good few answers - such is the nature of the internet.

If the problem has been resolved then please follow the link to the forum thread and mark it as Solved but please give us a clue how you did manage to solve it and also use the button under where you type stuff in rather than giving me karma credit points for just sending this note to you.

Apologies, good luck and many regards from
Tom :)
