No sound on a CF-52 Toughbook

There is no sound coming out of my speakers. Yet my speaker icon in the task bar says they are at 100%. I have tried all the volume controls. I have reloaded the sound drivers a couple of times. THe system says I have conexant 20584 smart audio HD and also ATI high definition audio device. In the device manager it says both are working properly yet I can not get any sound out of my speakers or my ear phones.

SOURCE: CF-51 no sound, drivers installed looks fine

If you go to the device manager and under the details of the unknown driver with the excalmation it says something about mat0019, it's most likely a problem that you don't have your hotkey drivers installed. On the CF-51, you have to have the hotkey drivers in order for the sub-functions of the F-Keys to work (the blue label like brightness, switch monitor output, and SOUND CONTROLS). Even if you have the appropriate sound driver, you will not have sound until you install the hotkey drivers as well. You can get them free from the panasonic busines toughbook support website. You'll have to register. There will be three hotkey related drivers. You HAVE TO INSTALL THEM IN ORDER. First do the hotkey appendix, then settings, then driver. Make sure to restart the machine as requested by the install program during the various installations.

SOURCE: my panasonic cf-52 speakers doesn't work

I had the same problem, I also noticed when I used the FN key the display didn't as well. First download new drivers for the HotKey Device, if you have old drivers on you laptop delete them when you try to re-install it always seem to go to those first. Uninstall the drivers for the HotKey Device and then re-install the drivers. Once complete restart your computer. Run HKeyapp, when I finished my FN key functioned normally again and my speakers were working..Hope this helps

The speaker on toughbook CF-30 quit working when I pressed function key and f4

If you have the speakers on and at the same time plug in a head set, the head set overrides the audio output. Make certain the Audio OUT is clear. Look to the Speak setup at the lower right desktop screen. Right click and check the Volume and Settings. Make adjustments from there.

Can't get sound to work

Which OS are you using. Anyhow on the task bar see if the speaker icon is crossed, if yes click on it and deselect mute. If not seen then press left arrow on the task bar, you will find speaker icon, unmute it.
See whether the speaker connection is properly plugged into the green socket marked Output.

Laptop speakers are not working. no sound comes out

Go to Control Panel, look for sound, choose internal speakers. Do you have a little speaker icon down on the lower right of your screen in the task bar? If you do click on it, and turn up volume.

Acer speakers- no sound!!!!!

Check the socket of your speaker to the computer if they are on the right socket.
Re-install the sound driver of your computer if you dont see an speaker icon at your task bar usually found at the right side of the task bar.
