Windows 10 Sound Card driver for Pavilion dm1z-3200

[russd]

I upgraded this PC from Windows 7 to Windows 10 about two years ago.  The sound has been working OK. Now I just had to reinstall Windows 10 due to "BOOT DRIVE INACCESSIBLE". Everything seems OK now, except there is no sound. In Device Manager, there is an unknown  device. I suspect it's the sound card, and that I need a driver. Any help would be greatly appreciated!

Hi:

The only suggestion I can offer would be to try this W10 IDT audio driver from a newer model notebook. 

Install and restart the PC.

This package contains the driver that enables the IDT High-Definition (HD) Audio in supported notebook models that are running a supported operating system.

The unknown device is probably something else that needs a driver.

Please post the hardware ID for it so I can post the link to the driver you need.

Use this guide for how to find the hardware ID for a device...

Paul,

I am embarressed to report that I just discovered the sound had been muted. It is working fine now.

As regards the unknown device that showed up, the hardware IDs are:

ACPI\VEN_HPQ&DEV_0004

ACPI\HPQ0004

*HPQ0004

Any assistance on identifing the dvice and obtaining the correct driver would be most appreciated.

Glad the sound is OK.

Here is the link to the driver you need...

This package provides the HP 3D DriveGuard software for supported notebook models that are running a supported operating system. HP 3D DriveGuard protects the hard drive by "parking the heads" if the notebook is accidentally dropped or is abruptly impacted by another object.

Thanks, Paul! That fixed it!

Is HP 3D DriveGuard the same as this System device I can see:

HP Mobile Data Protection Sensor?

You're very welcome.

That is correct.

The HP 3D DriveGuard is the trade name for the HP Mobile Data Protection Sensor.
