I have an Inspiron 8200.  When I play audio on my computer (through iTunes or even listening to a CD), the sound starts to get really garbled!  However, when I pause the music and then play it again, its fine for a while, and then gets garbled again!
 
I've checked the sound preferences and ensured that I had to option "Laptop Stereo Speakers" selected.  I also downloaded the latest crystal audio driver that was in the knowledge base.
 
Restarted my computer, and still the same problem.
 
What's wrong?
