You state that your sound on everything else is ok, meaning you've tried other
applications and it works, but not on WMP. Open WMP and check near the
bottom of the window for a volume slider, make sure that it is not slid all
the
way to the left (off). Then, to the left of the volume slider is a button,
now
hover your mouse/cursor over it and you'll see it is a "mute" button, make
sure
it is not set to mute (sound off). Happy putering and holidays. :~)
