HDMI audio output remains crippled with the Xbox 360 Elite. The Xbox 360 Elite, even when connected to HDMI will not output uncompressed multi-channel audio. Xbox 360 HD DVD users hoping to enjoy the full glory of lossless HD DVD audio formats via HDMI should look elsewhere.
It’s hard to tell whether or not this was an early April Fools joke, but it wouldn’t be much of a good one so I am leaning towards no. I am not sure how tempting an HDMI Xbox is going to be if it doesn’t deliver lossless audio. It might not matter to most, but the console is selling for a premium, so why wouldn’t they adopt a newer standard?
