'Ordinary' Users Unable to Change Audio Volume
I'm new here. Please be kind :)
It seems that some time since before Easter our pupils have no longer been able to change the volume settings in Windows 7 SP1. The icon appears in the system tray, but clicking on it garners no response whatsoever. It doesn't seem to matter whether it's a Realtek, SoundMax or IDT, our restricted users just can't do anything. Staff and Admins are okay, although they do have access to Control Panel which the pupils don't, although this wasn't a problem in XP. It's a multipurpose (if slightly underprepared) sysprepped image that we just add the drivers back to afterwards, and works like a charm on any machine we put it on... until now...
Has anyone else come across this problem lately?
