I'm trying to find the easiest and most affordable way to get digital audio and video to HDMI from my Mac Mini to my Sony TV. Right now I have Mini Display port to DVI to a DVI/HDMI cable with the audio being an analog Y cable. Would this converter work? It shows DVI and SPDIF on one side, but HDMI AND SPDIF on the other. Is the SPDIF output optional? Does it get transferred with the HDMI? I've seen the Kanex DVI/TOSLINK to HDMI. That would be ideal, but it's gone up to $70 now.
