Is there any way to lock the sound controls?

I am a middle school teacher and in my lab, the kids keep going in and adjusting the sound. They either turn it all the way up, all the way off or mute it. I have been hiding the sound control on the taskbar, but they still adjust it.

I would like to be able to lock the sound control so they do not have access to it in any way. Is there any way I can do this?

I am OK if it basically locks it down, I just want to make sure the kids have full access to the internet as needed, the programs they require and the ability to save as needed.

Thanks

Randy

Found this possible solution over at this forum: Windows XP Pro SP2 - Lock Volume so kids can't change it. - Tech ARP Forums

Hide Sound And Audio Devices Icon
1. Click Start, click Run, type mmc, and then click OK.
2. Click File, and then click Add/Remove Snap-ins.
3. Click Group Policy (left hand side), click Add, and then click Finish.
4. Click Close, and then click OK.
5. Expand User Configuration, and then expand Administrative Template.
6. Click Control Panel.
7. On the right pane of the Policy menu, double-click Hide specified control panel applets policy.
8. Click Enable, click Show, click Add, type Sound And Audio Devices to deny access, click OK, and then click OK.
9. Click Apply, and then click OK.

Well, I tried that and got nothing from it. It was worth a try. I am wondering if maybe it has changed slightly for Windows 7.

Basically when I logged in, I was still able to access everything. I do think we are close though.
