If I'm wrong, let me know and I can pull out my svcpack.inf files.

This driver is included in DriverPack Sound B, but in order to install it I first have to point it to the "hdaudio.sys" file in my i386 directory of the Windows installation. After that, then it is able to install correctly. Anyway to do this automatically?
