audio isn't working.
my audio is muted and i can't change it. it won't let me put the volume up or down using the F3 or F4 button. and when i try to un-mute it using F2, nothing happens. the volume panel comes up and tells me there is no sound because it's muted. and when i try to change the volume from the bottom right quick setting panel, it won't allow me to drag the volume to the right.
