Laptop sound not working after moving from Mandrake 10 to 10.1 (fresh install)

Hello Everyone:
Since I installed (fresh) Mandrake 10.1, I have no sound from the built in speakers in my laptop. With old version 10.0, the sound worked fine right out of the box. Symptoms: KDE (and Gnome) THINK sound is playing, only there isn't any from the speakers. I checked the mixer and all volumes are are 80%, nothing is muted or turned down. When I play music files, the visualizations show that Amarok THINKSS it's playing the song, only there's no sound. This may be a problem with the newer kernel, because I had the exact same problem with the latest SUSE and Fedora Core, but when I reinstall Mandrake 10.0 , it works just fine!
Here is the results of lsmod, if that helps:

Looking at /var/log/messages, I don't see any errors: Here are the relevant lines:
Apr  7 15:59:02 localhost kernel: intel8x0_measure_ac97_clock: measured 49491 usecs

Apr  7 15:59:03 localhost sound: Setting mixer settings succeeded
Apr  7 15:59:03 localhost xfs: xfs startup succeeded

DMESG also doesn't show any errors.

Any help will be greatly appreciated. I don't want to go back to 10.0 at this point.
