my question was really to do with how the sound got from the video
card to the hdmi cable, given the intervening DVI step, when DVI is
not supposed to be able to carry audio.

As I see it the audio passes this route on these cards:

MB-->graphicscard-->DVI-->DVI/HDMI convertor-->HDMIcable-->TV (or amp)

How does the audio pass through the DVI cable to the HDMI cable?
