Question about Panasonic Toughbook CF-51 Notebook
Hiya, Snods. I recently aquiared a second hand Panasonic CF-51 laptop who's operating system had been reinstalled, and am having great difficulty getting the sound to work. I ran across your post from March and was wondering if you have had luck since then in getting the sound to work on your CF-51. I'm signing up for this site to mail you about it. Cheers
I recently tried a dual boot with Windows7/Ubuntu 9.10. I lost audio despite all efforts in both of those operating systems until I reinstalled XP.
Still I had no sound until I installed a correct HOTKEY driver off the panasonic web site. Apparently there is an important switching function by this driver (?!) that is required. BEWARE OF THIS!
My system: CF-51LCMDDBM Mk2ll

You can download the XP drivers from the panasonic site. CF-51 got many flavors and be sure that your model numbers are at hand when you retrieve the factory installed drivers.
Delete all SigmaTel drivers from the registry hardware section. This would help reinstall the correct driver. The presence of these wrong registry values prevent successful installation of the factory drivers.
I have installed se7en, vista and XP successfully. The sound is really problematic since Dell and Gateway laptops use similar sound chips and offers drivers on the net... but they don't work at all. The Gateway driver seems to install perfectly from device manager report, but only the mic works & no sound.
What I do is install the factory provided drivers in XP compatible mode and then use windows update to download the latest SigmaTel drivers (se7en pre-beta). Windows got a more compatible driver but it can only install over the original since the chips cannot be recognized.

The cf-51 use several audio drivers depending on which model you have.
Make sure that you have the correct drivers.
If unsure , just shout.
If the drivers do not work, Sometimes the headphone jacks are damaged and that board will stop the sound from working.

I recently had a cf72 with sound problems, turne out to be the sound board. Make sure that it's not a driver issue first. You may have a driver glitch or the wrong sound driver.
