I just built an HTPC wiith Vista64 SP1 and am having a problem. I have a DFI LanParty X58-T3H6 motherboard and a VisionTek Radeon HD 4870 Video card with HD audio. I have an HDMI cable going to my Sony AV receiver and all I get is Stereo Audio. The subwoofer never comes out of standby nor does the AV receiver indicate anything but a stereo input.
I have the RealTek HDMI audio device installed and it says it is working properly under Device Manager. Under properties all that is offered is Stereo speakers. Surround Sound is shown as an option but it is grayed out and not selectable. All drivers are up to date as of two days ago, and I have the on-board sound of the motherboard disabled in its BIOS.
Other HDMI devices, such as my XBOX 360, do surround sound through the Sony AV receiver.
VisionTek support told me to install the HDMI RealTek driver, but that's all the help they've been able to give me.
If anyone has some additional insight on this, it would be most appreciated!
Thank you!
