The sound on this machine worked pretty well until a few days ago (okay, so sound is not the very most important thing to me, but, the lack of it is getting old).
When I click the speaker icon it always says "Mute", when I set it to "Unmute" the slider goes to zero. When I move the slider off of zero, the status goes to "Mute". So, does anyone know what's going on with my system?
