Hello and welcome to the forum!     smile

That may be because this solution is for NT5.  Please start a new topic in the NT6 section of this forum.
Doesn't HP have support for their audio solution?

Also, are you integrating DriverPacks or attempting to install post-Setup with SAD3?


Thank you., but still very new to the forurm, I'm not sure where exactly is the NT6 section.. 

And HP support did not have any solution that I can find.     

even with the factory install setup fresh, I notice there is what was call "HP Audio", but no sound..   its unable to detect the IDT hardware or Nvidia audio...

I had the exact same issue in our Copmany. Rambling days with it. I opened a HP CASE an got an Answer that worked for me:

1. delete a Regkey: HKLM\System\CurrentControlSet\Services\AEAudio
commandline: reg delete HKLM\System\CurrentControlSet\Services\AEAudio /f
2. Reboot the Notebook
3. Installation HP Audio Driver for the Elitebook 8540w  (sp46721.exe)

Audio works now! :-) We can Deploy the Elitebook 8540w with Windows XP SP3.


I'm running win7 64, I had done a factory restore and yet my idt will not install.   I look at the Reg, but there are no regkey as above to delete .    has anyone have any other help on this    Please help   also have hp 8540w
