Hey there...

So I have been reading posts about no sound on this site and it has been really helpful. I reinstalled drivers and a couple of other things...and it worked. The very next day it went right back to having no sound. Any more suggestions?? I'm getting to be more than frustrated. The sound icon on bottom of screen is "x"ed out and when I go to sound devices it says no sound devices are installed.

Any info would be great...

Try update the sound driver (un-install current sound driver then download newer version then install it).

Thank you for your reply! I did just as suggested but it didn't
work. I believe the name of the driver is conexant?? Anyway,
it still says it's missing. :-( it's so aggrevating!! I'm just hoping
I'm uninstalling/installing the correct driver.

Any other suggestions are appreciated!

Thank you!! Kristi

The two most frequent reasons sound software doesn't work properly are the wrong software was installed, or the right software was installed the wrong way.

There are many different Conexant sound chipsets - you must install the right software for the chipset. Get the proper sound software from the HP site in the downloads for your model.
If there is more than one, use the Product number on the label on your laptop to find the software specific to your model configuration, instead of the model number, on the HP site.

You DO NOT install drivers for a sound device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.

If you DID install drivers that way, go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting, and install the software the right way !

The same applies no matter when Windows finds New Hardware !

If Device Manager shows the sound device is working properly, you may or may not hear sound when you plug in headphones, but you don't hear sound when you unplug the headphones...

The headphones jack has a mechanical switch inside of it. It's supposed to disable the sound from going to the speakers built into the laptop whenever you plug a plug (on a cord) into the headphones jack.
If you have plugged into the headphones jack a lot, it's common for that mechanical switch to malfunction. You could try plugging a plug into the headphones jack, wiggling it, then pulling it out, that may get one or both speakers working, but the only real solution is to replace the headphones jack - that's frequently replaced item done by laptop repair places.
OR - if headphones produce sound, you could make do by plugging amplified speakers into the headphones jack.
