Add volume control to desktop panel indicator?

I recently upgrade to Ubuntu 10.04 and I noticed that I'm no longer able to add a volume control to my desktop panels. When I right click the panel and choose "Add to panel" there is no longer a volume control in the list.

How do I add a volume control to my desktop panel?

You want the the option from the list to add an "Indicator Applet".

This is because from Ubuntu 10.04 there has been a push for panel items to use a new system for panel items.

If adding the "Indicator Applet" appears to make no difference, you should try to install the package indicator-sound which contains the sound indicator.
