I think my sound card has been accessed. It startup with sounds. And I
can play music. But when I click the Volume Control locate the Panel.
It shows:

the volume control did not find any elements and/or devices to control.
This means either that you don't have the right GStreamer plugins
installed, or that you don't have a sound card configured.

You can remove the volume control from the panel by right-clicking the
speaker icon on the panel and selecting "Remove From Panel" from the
menu.

How to solve.
