Install the audio driver for Intel DG965WH motherboard in Windows 10

Why would you want to install the driver? There are two main reasons, first to get front header audio support and secondly for the "Stereo Mix" feature in order to capture internal audio with some installed software that captures audio. (Those are the features that the default Microsoft driver doesn't support, I haven't tried but if you can't use Dolby DTS sound, this may fix it).

Do this under your own risk, these are old drivers from 2009 not made for windows 10, you may want to make a system backup or restore point before trying this, in case something goes wrong. I'm not responsible for any damage to your computer or software.

I'm posting this because I installed the drivers and they seem to work just fine on my DG965WH motherboard under Windows 10 64bit, the next method may also work for other Intel 965 motherboards (with the right drivers for the boards of course).

1- Get the drivers: The drivers from Intel may no longer be available so you may have to find them somewhere else. Here you can find them http://www.driverscape.com/manufacturers/intel/laptops-desktops/dg965wh/2602

Get the driver named "High Definition Audio Device", the one from 2009, the version is 6.10.20001.0 (I compared the file and this is the exact same file you would get from Intel). Do not double click the file, it will not get installed anyways because the driver interface is not compatible with windows 10 (beware do NOT install in compatibility mode, I warned you).

2- Extract the driver: You need Winrar to extract the file (go ahead and install Winrar if you don't have it), right click the audio driver file and in Winrar options click on "Extract to AUD_allOS_D20001.0x_PV_IDTGUI_v105_Legacy\". Take note of the created folder location.

3- Once the files are extracted go to "This computer", on the left pane right click "This PC" and select "Manage", go to "Device Manager" and on the right pane find the sound section and expand it, there you'll find 2 entries, right click the top one and click on "Properties", in the "General" tab make sure the "Location" is 0, if the "Location" is 2 or other number just check the other entry on the sound section, it should be 0.

4- Go to the "Driver" tab and click on "Update Driver", click on "Browse my computer for driver software" and browse for the folder you just created with Winrar, click on "Next" to install the driver.

The driver should be installed now, to check if it works right click the sound icon in the taskbar and click on "Playback devices", you should have at least these features (Speakers / HP, Headphones (RTC), SPDIF-Out (Rear)) if you dont see any of those, right click on the list and make sure the checkboxes are activated for "Show disabled devices" and "Show disconnected devices".

On the "Recording" tab you should see "Front microphone", "Rear microphone", "Input line" and "Stereo mix".

Note: The text between "quotes" may be different in your computer.

Restart your computer, then you should see the icon in the taskbar, go to options and disable the taskbar icon to reduce the risk of anybody changing the settings. I strongly advise you not to change any other setting there to avoid problems (the equalizer and other options won't work anyways).

Edit: Windows 10 no longer lets you replace drivers this way but what you can do is uninstall both audio entries in the "Sound, video and game controllers", then go to "AUD_allOS_D20001.0x_PV_IDTGUI_v105_Legacy\WDM\Vista" and double click "suhlp64.exe", Windows smartscreen will give you a warning, ignore it and install the driver.

* To configure surround sound just go to Control Panel/Sound, right click the speaker icon and select the "Configure Speakers" option.
