    Also, if you don't have Hotkey appendix (it's normal for Win7 x64) - install it, unmute sound and uninstall it again :)

    I am adding to this old thread because it's still the top result for this problem on Google!

    My CF-19 mk3 had exactly the same problem - no sound from the internal speakers but perfect sound through the headphone jack. All drivers claimed to be up-to-date and functioning. To make matters even more confusing, occasionally the internal speakers DID work, despite there being no changes to settings etc.

    I contacted Panasonic support and they advised me of the following:

    In my case, I found that I did not have Hotkey Appendix Utility on my machine, and Hotkey Settings existed but was not installed. I downloaded the missing driver from the Panasonic support website, then followed the instructions above.

    Immediately on completing the steps, even before rebooting the laptop, the sound was perfectly restored. It now appears to be working reliably.

    Hi guys,

    Old topic I know, but I have discovered a very simple workaround that you can do in less than a minute and doesn't even need admin or drivers :)
    I accidentally discovered it myself after messing around and looking for answers a fair bit.

    The method is (without anything plugged into external jack of course):
    1) play something that has audio (eg - an mp3, youtube video, whatever) and confirm the computer thinks sound is playing
    2) while the sound is still "playing" (though you cannot hear it), put the PC to sleep via the regular methods of doing so (both shutdown menu/sleep and closing the lid when set to sleep appear to work fine).
    3) when you resume the pc it appears to initialise the built in speaker as expected and it will play sound :)

    For reference:
    I have a cf-19 mk3 on windows 7 64 (and had a previous cf-19 mk3 - earlier mk 3 meant for distribution in a different country - for reference, current one is CF19-QJREX2M - US model with touchscreen, previous was CF19-KDRANCA - Australian market model with dualtouch screen)

    Appears to need repeating occasionally, I never had the problem before I first used headphones on either mk 3 (I now have only the QJREX2M)
    I will try what badgerlady suggests about hotkey appendix utility though... see if it makes it never happen again :)

    And some various rambling and thoughts on other toughbook topics:
    Lovely machines the toughbooks!

    Though the rubber keyboards irk me hugely, luckily like a number of other parts, the keyboards swap between a surprising range of options.. I am currently running a cf-18 keyboard on this cf-19 mk3 actually, to spare myself the frustration of the rubber backlit one whilst trying to touchtype - this is handy info for you to know :)

    I have also had a mk2 (CF-19FHNANAA) running win 7 64 for quite some time and run a few other cf-19mk2s and cf-19 mk1s on both windows xp and windows 7 (mk1s can be a right sod to set up win 7 on, and if you don't want pain avoid installing xp pro on a digitizer model mk3 ... at least if you want any working touchscreen/digitizer drivers.. darn stubborn thing... use xp tablet instead :)
    None of the mk1s or mk2s I have used has never suffered from this sound stopping error, but both the mk3s have.. and both resolved via this method :)

    oh, and a really useful fellow has packaged toughbook drivers into "one click" packages to make things easier for us toughbook fans.
    He appears to install them in the correct order and have assembled packs for the non-standard windows OS options for various models also
    And he includes instructions on making your own
    just google:
    toughbook one click bundles Brian Gonzalez
    and you will find them, tops fellow by the look of it - and nothing to do with little old me, I'm an enthusiast not a pro :)

    This is a great tip! That sound problem is often asked about.
