i have an Asus H97i running a i3-4150 and windows 8.1 Pro x64
My AV receiver is a DENON AVR-1612 and is DTS-HD & True-HD capable, connected via HDMI. However Windows Audio only shows DD, DTS and DD+.
I have installed lastest intel graphics and sound driver from the intel website (15.33.22.64.3621 英特尔® 下载中心)
I have installed GT430 and connect my av receiver via HDMI, it supports DTS-HD well. But when i use Intel Graphics, only support DD, DTS and DD+.
