Need a little computer help

Hi Kevin, is the volume icon missing from your system tray by any chance. Do you know how to access device manager? IF so check for an exclamation mark, question mark, or X on the sound, then we can go from there.

Found the Device manager but there are no exclamations,question or X's on it.
If i click on the icon it opens and when i have music playing it bounces up and down with the music but there is nothing coming from the speakers.
