SOUND IS GONE!

I just booted up tonight and found I have no sound! The volume icon in the taskbar has no volume bars in front of it.
So I tried starting the KDE volume and that doesn’t work either. Then I went to reinstall the KDE workspace and update and upgrade and no change. How do I get my sound back?

You don’t muted the sound by mistake? Is Phonon configured right in the systemsettings?
