Volume Icon Gone from Top Panel in Ubuntu 10.4
I am using the fully updated version of Ubuntu 10.4. The volume icon is missing from the top panel and adding the "notification area" does not do anything - I can double-click the icon, or drag it over, and nothing appears in the panel. Adding the "Indicator Applet" also has the same result.
I do not know what applet to add, nor do I know why the volume icon is missing.
The power icon, the network icon, the mail icon, and the rest of the applets are all there - only the volume icon is missing.
Also, when I press "fn + pg up or pg dn," it would usually change the volume and display a notification showing that the volume changed.
This does not happen anymore: no notification, no sound change.
I can still hear audio, but can not change the level. If you could help me with this, that'd be awesome!
