It's usually indicates more then one audio device in use.
In Win7 right click the volume icon
select Volume Control Options
Choose the preferred device and uncheck the others.

Hi davcon, I did say I would get back to you, well so far your diagnosis seem to be correct. I did have several sound devices running at the same time so, I chose the preferred device unchecked the others and I have not heard any skipping. If anything does change, you'll be the first to know. Thanks bunches!
