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 15:59:02 localhost kernel: intel8x0: clocking to 48000

Apr  7 15:59:02 localhost alsa:  succeeded
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.

Log on as root and use the amixer command to set the volume levels
# amixer set Master 74% unmute
# amixer set PCM 74% unmute
# amixer set Headphone 74% unmute
# amixer set CD 74% unmute

You can go upto 100% in place of 74%. Also, once you have done this, you can login to your mixer and check the volume.

If you are using the KDE desktop, then you can launch kmis and set the volumes there as well. Normally, after using amixer, the KDE volumes need to be set.
