[Eug-lug] Trouble with sound system

[Robert M. Solovay]

I am running Kubuntu Feisty Fawn.

One of the usuer accounts on my machine has sound. The other two do not. 
When I go to the Sound System System Settings it is identical on the two 
accounts I am currently working on. One of the accounts on which sound is 
not working is the one originally installed on my machine.

Is there some place other than the sound settings whee a mute could be 
turned on? What's the next step in trying to fix this?

Thanks,
