Sound Problem

["Stephen P. Molnar, Ph.D." <s molnar sbcglobal net>]

I have just switched desktops from KDE to Gnome and have a question with
regard to sound.

Sound works without any problems as root, but when I attempt to use
sounds as a user I get a message:

Volume control is unable to run correctly.

Unable to open audio device '/dev/mixer'.
Please check that you have permissions to open '/dev/mixer'
and that you have sound support in your kernel.

I apparently have a permissions problem, but am not sure.

Any assistance will be greatly appreciated.

Thanks in advance.
