Hi There, I've been searching high and low and cannot find a MDP-to-HDMI cable (not adapter) that supports audio out for use with my MBP. Does such a cable exist, or do I absolutely need to use an adapter? Looking for the cleanest solution possible. Thanks. EDIT: Looks like I found a cable on eBay. They do exist from individual cable-makers, but it looks like they don't exist from cable manf's like Monoprice and Blue Jeans Cable.
