I need help with 64 bit audio drivers

I've installed Windows 2008 x64 on my HP Pavilion zv6252EA.  Everything works great but I can't get the audio drivers to startup.  A search round the internet and it seems many people are have audio problems with the 6000 series.  I've started the audio services but the drivers get an error and the device can't start.  I've tried many driver versions.  I have a feeling it may be down to Unsigned Drivers - does this prevent them starting on 64 bit Windows - is there a way round this like a registry hack?  Is there a firmware update for the motherboard - where are these found?

I found this link when searching on google. I'm not sure they are for x64 though.

You can try this driver finder utility.

http://www.innovative-sol.com/drivermax/

However, I'm not sure it supports x64. But otherwise a very good driver utility.

The findmysoft driver failed to install.
I tried Drivemax but it reported all my drivers were up to date.
What's the story with driver signing - does W2008 insist on this - can it be switched off?

This is the vista command for disabling driver signing. It should work in 2008 too.

Bcdedit.exe /set nointegritychecks ON

To turn them back on

Bcdedit.exe /set nointegritychecks Off

Reboot for it to take affect.

Couldnt get driver to start.  Might there be a generic driver eg by AMD that would get the AC97 working?

Try installing the south bridge drivers. I think this is the one you need.

I've got the sound working.
I found the drivers hidden on the HP site at http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&swItem=ob-51288-1&jumpid=reg_R1002_USEN
If you run the exe it will fail.  The defalt place where the setup program will be extracted is c:\swsetup\sp35558\.
You need to install the driver as follows:
1) Start the "Device Manager", right click the broken Audio Device an select "Update Driver Software".
2) Select "Browse my computer for driver software, then click "Let me pick from a list of device drivers on my computer".
3) For audio, select the device type "Sound, video and game controllers" and select Have Disk, then browse to manually locate the corresponding .inf file for the audio driver eg c:\swsetup\sp35558\.
4) Select that audio driver and install it, if you get a warning about it not being compatible like I did, ignore the warning and continue with the installation of the audio driver.
5) Restart the computer if it asks you to.
8) The speaker symbol on the bottom right of the task bar should now lose  the Red Crossed Circle and sound should be enabled

Glad to hear you found the driver. I wish HP would do a better job at making things easy to find. Thanks for the info.
