Trouble with audio over HDMI

MikeInEburg

I have a BT3 Pro II-E and I'm having trouble with audio via HDMI. Video via HDMI works fine.  In device manager, "Sound, Video and Game Controllers", there are no HDMI drivers listed.  In Device Manager "Audio Inputs and Outputs", only option is "Speakers (Intel SST Sudio Device (WDM))".  How can I add in HDMI as an audio source?  Note that analog 3.5 speaker output works fine, it's just not my preferred device.  Thanks!
