    There was a post from OHLIP I think. U have to install the sound driver in correct order, so that u can adjust that the internal speaker has to make some noise instead of the headphone plug.

    Yep, this is one and there was another one. I learned from his posts, it is not every time a bad connection inside the switch of the headphone plug, mostly it is a problem caused wrong driver installation. U have to go close to the installation instructions from panasonic, which u can find on their website.

    Something else to try. I have a CF-19 that if I ever mute the speaker, the ONLY way I can get sound back is to take out the main battery, take off the bottom of the computer, unplug the CMOS backup battery for a few seconds, and then plug it back in. If I use the volume control to lower the volume to zero, it is ok, but using the mute button is a no go. If all else fails, try that trick. No clue why it works, but it does, and I've used it a couple of times on that computer.

    Welcome to the Panasonic Toughbook Forum

    I just moved your post into a thread of it's own. This way maybe other T4 owners will see this.
