HOW TO FIX HD AUDIO/UNKNOWN DEVICE/DEVICE WON'T START LENOVO H320 Win 7 64-bit

Fix for - HD Audio devices won't start or you can't load correct driver. Lenovo H320 - Win 7 64-bit I-3 processor. 5 series/3400 chipset

Here is a working procedure to fix the problem when you install windows 7 64-bit and can't get the correct drivers installed for the HD Audio devices 1)Realtek AC97 HD Audio device id = HDAUDIO\FUNC_01&VEN_10EC&DEV_0662&SUBSYS_17AA3604&REV_1001
and 2)Intel HD Audio device id = HDAUDIO\FUNC_01&VEN_8086&DEV_2804&SUBSYS_80860101&REV_1000 Regards >>> Sucromatic

 

 

For an IBM LENOVO 320 with Windows 7 64-bit Home Premium Version download these drivers to a directory in a second partition to prevent this nightmare from happenning in the future.

1)AC 97 high def audio version

Realtek HDA 2.67found on http://wikidrivers.com/wiki/Main_Page or at www.realtek.comon right of screen on homepage and

2) Intel HD GRAPHIC and HD Audio version

Intel GMA 15.22.52.2559 (Vista/7) 14.46.8.5387 (XP)

found on

http://wikidrivers.com/wiki/Main_Page.

Select your OS and and whether 32 or 64 bit. I recommend the .exe version as it works very smoothly. Uninstall HD AUDIO DEVICE or whatever it is called maybe "unknown device" with ac97 device ID "HDAUDIO\FUNC_01&VEN_10EC&DEV_0662&SUBSYS_17AA3604&REV_1001." Afterwards install AC 97 HD Audio Driver.

 

After install reboot and wait till computer completely starts.

Now uninstall Intel HD Graphics or your graphics device. When you get the uninstall box open, select delete the driver software for this device and then OK. When prompted to reboot select NO and Immediately start the install of the Intel GMA driver. Which installs both the Graphics Adapter and the Intel HD Audio. Reboot when finished and all HD Audio devices will be functional (hopefully). You will now have these versions installed. As shown in device manager/device properties/Driver tab

 

 

Now uninstall Realtek AC97 driver you first installed to delete annoying Red Lexmark/realtek icon in Notification area (If your computer shows it after reboot) and windows driver update will install a microsoft driver (shown below)that works without the stupid lexmark red icon. See below. You will now have these versions installed. As shown in device manager/device properties/Driver tab

Voila. Now go to intel and run a driver update scan and it will likely correctly identify your Intel pieces and offer downloads for any that are not current. Good Luck!
