No thanks, we want to pick a particular driver: Windows offers to automatically detect the driver that should be installed. Right-click the device you want to change the software on. (If the device name included a company name, I would infer that I had a vendor driver installed.) In this case, I have one audio device, and by the “High Definition Audio Device” name I deduce that I have the class driver installed. Type “devmgmt.msc” (without the quotes) to launch Device Manager.Įxpand the “Sound, video and game controllers” node and note the list of audio devices.

Occasionally, for troubleshooting purposes, it is useful to switch from one driver to the other… either to get the additional functionality provided by the vendor-supplied driver, or to see what happens if the class driver is installed. This driver is designed specifically for the hardware it runs on (as opposed to being designed to the standard) and so it comes with additional functionality. Usually systems come with a vendor-supplied driver installed. Windows Vista (and later) includes a “class driver”, hdaudio.sys, which should work with any such audio device. Most on-the-motherboard audio devices support the Intel High Definition Audio standard.
