How many Bloody Marys have you had? - Richard Faria, Temonmichi
Most people don't realise that HDMI supports sound transfer as well as video, it is a one cable fits all thing. There were a handful of graphics cards floating around the show, and as far as I saw, none put sound across the channel.

Sapphire added a SIL chip to the card to generate sound, and pumped it out across the link. Interesting, cool, and so far, quite unique.µ
