The very latest Windows 8 OEM installer DVD comes with a complete built-in Windows 8 certified Intel graphics driver, including "graphics properties". In other words, with the latest OEM and an Intense PC, you get a complete installation without using Compulab drivers. And, of course, it only supports HDMI sound.

If you add the Compulab realtek sound driver in compatibility mode, you get the old scratchy audio from the analog output jack, using a volume setting of around 8. And, of course, you get super 41000 analog audio using a USB external sound card and the built-in Windows 8 driver, with almost unmeasurable extra overhead.
