I'm almost certain that the original Xubuntu 12.04 installation includes 
the Indicator Plugin in the panel. If Indicator Plugin isn't there you 
can add it back.

It has icons of a speaker, an envelope, and a symbol indicating your 
network connection type. I'm referring to the speaker icon in that group.

You can also run "Volume Control" from a terminal. Enter: pavucontrol

That doesn't mean you don't have something else that's a "sound card." 
My video card has HDMI, which includes audio and is treated as an 
additional sound card. But in any case, the volume control program will 
allow you to disable any sound cards you don't use.
