Every day I share a number of Mac computers with many users. I need to be sure that none of them are able to modify the audio input settings of the machine.

The Audio Input preference in System preferences must remain on built in, and the input source (in the "AudioMidi Configuration" utility) must remain set to Digital Input rather than Analog Input.

Does anyone have any ideas how I can do this?

The Macs are Power Mac G5s and Mac Pro 8-core machines. The Mac OS X installations range from 10.4 (Tiger) to 10.6 (Snow Leopard).

Consider giving them regular user accounts that are not allowed to open System Preferences via Parental Controls. If you want to treat them like children, use the functionality designed for it. – Daniel Beck May 18 '11 at 17:05
