help! mic on ibook not working! :(

I'm helping my mom troubleshoot this problem so please bear with me...

we tried to skype yday and it turns out the built-in mic on her 12"iBook is not working. I barely hear some faint static, but for the most part it was dead. I had her go to System Pref->Sound and test the mic and the mic level was not moving when she spoke. Does this mean the mic is dead?? or am I missing something? Is there a USB mic available that she can use?

Please help!!!!

Go back into the Sound preference pane and click on the Input tab. There'll be an option to lower or raise the microphone input volume. See if that helps.

Click to expand...

I'm pretty sure she looked into this yday and she said the input volume was in the middle.....i.e not mute. so that's not the problem.......
