HI;

 

By any chance do you have an add-on audio card with HDMI out?

 

If so, you need to go into your BIOS and in the device configurations menu there should be an onboard audio setting which is probably set to Auto right now. Change that setting to Enabled, hit the F10 key there and upon saving your changes and exiting the BIOS.

 

Now you should have sound.

 

If you do not have an add on video card with HDMI out, did you first install  the chipset driver before you installed the audio driver?

 

If not, here it is: Install and reboot.

If you still have no sound, then I recommend you uninstall the audio driver, and install the MS UAA Driver for XP SP 2 at the link below, reboot and then install the audio driver afterward and you should now have audio.

If none of that works, I'm afraid I don't have any other suggestions for you.

Hi:

 

Sorry none of that worked. I have no other ideas as to what could be wrong. If the PC is still under warranty, I would contact HP Support and get it repaired.  Maybe it is a hardware problem of some sort.
