I just bought an Asus M5A97 R2.0 motherboard. This motherboard has a Realtek 887 8-channel high-definition (Azalia) audio device. It has two "SPDIF" outputs, one in the form of an optical S/PDIF port, labeled "SPDIF_O2", and one in the form of a header, labeled "SPDIF_OUT". (The SPDIF_OUT header has these pins: +5V, [blank], SPDIFOUT, and GND.) The BIOS has a configuration option that allows you to set the "SPDIF Out Type" to either "SPDIF" or "HDMI". The S/PDIF standard does not support 8-channel high-definition audio. S/PDIF only supports 2-channel high-definition (uncompressed) audio. However, HDMI supports 8-channel high-definition audio. Therefore, I would like to set this option to "HDMI" and connect an HDMI cable to my computer in order to get 8-channel audio output.
How exactly can I connect an HDMI cable to my computer carrying 8-channel HDMI audio output from my motherboard, suitable for connecting to an audio receiver, for instance? I have an MSI Gaming N760 TF 2GD5/OC video card, if that matters. (I know some solutions pass the audio through the video card, though I don't prefer that if possible because I'm already using that for video and I want to send the audio elsewhere.)
This question is NOT about getting HDMI video.
