My old TI Pro (MSDOS but not PC compatible), has a high-pitched
squeal coming from its speaker which behaves in much the same way.
It always squeals when the machine is idle and waiting for keyboard
input.  It is quietest when the screen is clear and the processor is
busy (not waiting for input).  The speaker was too loud anyway, so I
put in a volume control.  Turning it down diminishes the squeal.  
Since I put the machine under my desk, I can't hear the squeal at all.

regards, Larry
