No earphone jack acknowledged on HP ProBook 6440b


I have a HP ProBook 6440b running Windows 7.  The in built speakers work fine, but when I plug in headphones it does not seem to recognise these and continues to output sound via the in built speakers.

I have included a screenshot that shows sound output on the laptop

I'm guessing that I am missing a driver for the earphone jack, but unsure.  Any ideas on this would be great as it is a real hassle not being able to use my earphones. View of sound outputs on PC

There's no name in the sound card part it only states high definition digital audio not "Reaklek HD "
So I agree re- install your mainboard drivers.
Here's another guide to solving audio playback issues try this after you reinstall drivers
have you done anything recently with the OS?
Is this 32 bit or 64 bit OS?

Hi guys, thanks for the replies.

It's 32 bit OS, I haven't done anything to it, but my IS dept (who are next to useless) tried to put XP over windows 7 then reinstalled windows 7.  I'm guessing it was due to this that my drivers have got screwed up.

I can't get the drivers as it is asking for ftp name and password when you click on the download options on the HP site.  Any ideas?

I was using FireFox which the HP site doesn't work properly on.  IE only it looks like, downloading the drivers now
Are these systems imaged?
refs to> tried to put XP over windows 7 then reinstalled windows 7..really??
The mainboard drivers covers everything including the usb devices since your problem is the headphones not being detected
You may need to start clean if they are so useless lol
Take a look in device manager
open control panel then Control Panel\All Control Panel Items
device manager
go to view and show hidden devices
any yellow question marks or duplicates?
then expand Sound Video and game controllers
click on the audio driver then properties>drivers>update
Check your events errors see if anything is listed in there.
Here's a tool that's very handy to find your system specs and any problem devices
