Unknown Device - Looking for Driver

[PhilDouglas]

Hi

Could someone please help me locate the driver for the following unknown device on a HP ProBook 430 G3?  It's listed as a Multimedia  Audio Controller.

PCI\VEN_8086&DEV_9D70&SUBSYS_80FF103C&REV_21

PCI\VEN_8086&DEV_9D70&SUBSYS_80FF103C

PCI\VEN_8086&DEV_9D70&CC_040100

PCI\VEN_8086&DEV_9D70&CC_0401

Thanks

Phil

Hi, Phil:

It is part of the Conexant HD audio system.

If the above driver does not automatically install that device, go to the device manager, and click on the multimedia audio controller needing the driver.

Click on the driver tab.  Click on Update Driver.  Select the Browse my computer for driver software option and browse to the driver folder that was created when you ran the file.

That folder will be located in C:\SWSetup\sp72909.  Make sure the Include Subfolders box is checked and the driver should install.  Then reboot the PC.

The driver setup information file for the hardware ID you posted is included within the driver package.

I've been in touch with HP Support since and it wasn't a driver issue itself.

I had to take the following steps to get it to work:

*  Start the BIOS and disable Intel Smart Sound.  Save and Exit

*  Open Device Manager and uninstall the Unknown device.

*  Scan for Hardware changes and then update the driver

All working now.

Thanks

disable Intel Smart Audio in the BIOS
download drivers here and install them

open device manager and uninstall the unknown device.

scan for hardware changes and all is OK.
