CF-19 - Loss of sound from internal speakers

It's strange that the answer is still not here.
Just rename this file
C:\PF\Panasonic\Hotkey Appendix\HKEYAPPV.dll
to something like HKEYAPPV_old.dll
and your sound (including mute control) will work forever

 

Do the hotkeys still work after doing this?

I personally almost never use the hotkeys, but they are very important to others

 

Of course they work
And you can always rename that file back if you need it. But you will not )

P.S. I think you'll have to restart after renaming

 

Stolen from the web.

What is Hotkey Appendix?
This applications shows the available hot keys for the device. A hot key is a combination of keys or a single key on a keyboard that, when pressed at one time, performs a task (such as starting an application, launching a web browser, etc.) more quickly than by using a mouse or stepping through a series of menu items. A hot key control is a window that enables the user to enter a combination of keystrokes to be used as a hot key.

too many letters ))

 

I had this happen to me while working on a CF-29.
While getting ready to swap out a hard drive I used the hot keys to mute the sound.
It must have changed some setting in an eprom to totally disable sound because I was not
able to get sound from the unit until the hot key drivers and apps were loaded again so
I could then enable the sound again.

I like ramble-on sentences :hi2:

 

Quoting this because it has a cross platform application. (Windows and Linux)

I have had a problem with a Linux program (actually two un-related problems) that were fixed by going to stand-by and return. (Close lid and re-open)

Whether it will fix your sound I know not.......it's just interesting.
