Volume control not working

My volume control in the tool bar is white instead of blue, and I don't have any volume and can't adjust it. If I log in as a new user, it works fine. I have repaired disk permissions, and that didn't help.

Try trashing this preference file and reboot.

HD > User > Library > Preferences > com.apple.systemuiserver.plist

A few other things to try out...........

Did you restart your computer after repairing permissions and trashing the previously mentioned .plist file?

Boot from your Install DVD #1 & run the *Repair Disc* setting.

Does it work if you login to another User account?

I just did the disk permission and .plist together and the smc. Still not working, but before I go on remember I can login as a "new user" and the volume works fine. I'm on the road, and using my iPhone for Internet. I don't have my startup discs with me. Thanks for the help. Tracy

OK, then your problem is most likely in your main User Library. Try dragging the whole preference folder to the desktop and rebooting. If it works, start dragging a bunch of preferences back at a time and retest until you find the corrupt preference file. Note: you can log out and back in vs. rebooting (when testing) if you wish.

Okay so I put my preference folder on my desktop, but I can't delete the original because it says preferences can't be modified or deleted because it is required by mac os x so how does the laptop know which preference file to use because there is still no volume. Thanks again, Tracy

Before you take a screwdriver to your computer tell us if you are getting sound out.
Secondly, check in sys prefs what is your audio output set to. If you have nothing connected the output should read - internal speakers.
