Description of problem:

I installed a clean F9 on a Dell Precision M70, and there are no sound out of
the speakers; it all appears in the headphones whatever I'm doing. It all worked
fine and out of the box in Fedora 5/6/7/8. I cannot see any errors in the
pulseaudio -vvv output nor anywhere else. I have updated all components and
there are still no changes.
