ahhh you didn't mention the students. I'm a teacher myself, so I sympathise. Just asking them not to do it won't work
OK here's another suggestion (though I've never needed to try this myself):
Go to the account students use to log in to the Mac, select "Parental Controls". I think that gives you various options.
You could withdraw admin rights from all students unless they sign a declaration that they will not mess with the system preferences. That way, only authorised people would be able to admin the system and might have their authorisation withdrawn if they abuse it.
Or maybe there really is some add-on that will turn the audio off, for yourself only. I don't know of one but maybe somebody else does.

Hi mahender negi;
If you have allowed a student admin privileges then you have probably shot yourself in the foot. Once you give them the rights all bets are off.
First off, may I ask why students have admin rights in the first place?
If they have admin, you can't do anything. Whatever you do to the system they can undo, as they have unlimited rights (and if they know what they are doing, can escalate to root). Until you give them standard accounts.
The one thing you can try, while reversible, is getting rid of the Kernel Extensions for audio. There are instructions here. This will essentially disable the on-board audio all together. (I said it's reversible, but I doubt many students will have any idea how to fix the "problem" of no audio. This is also a set fix. To change it back, you need to put the kext files back and reboot.*
*I would try this on one machine first and test.
You're best fix would be to use managed accounts however.

There should be a script to disable or mute sound in MAC OSX
I want to use that
It doesn't matter. They have admin... they can undo anything.
I have all these related to audio:
If that doesn't do it, put them back and try another method. I'm not sure what other audio kernel extensions there are (or as to why that didn't work). You can try rebuilding the kextcache if you want.
