Actually more like FWAH! (random utterance of disappointment) @ M$'s cheap-tricking behinds!
I mean really? THEIR COMPOSITE/COMPONENT/VGA CABLES ARE DESIGNED IN A SUCH A WAY MAKING IT IMPOSSIBLE TO CONNECT A NON-MADE-BY-CARELESS-M$ HDMI CABLE WHILE HAVING THEIR COMPOSITE/COMPONENT/VGA CABLES CONNECTED TO THE 360 AT THE SAME TIME, BUT, THEY MADE A "OPTICAL AUDIO" CABLE THAT ONLY COMES WITH THEIR HDMI CABLE THAT WILL FIT IN THE 360 *inhales* FOR USE OF AN AUDIO SYSTEM...AND THIS OPTICAL AUDIO CABLE IS FEMALE...so you'd need male RCA cables to go into those...how wonderful...
Anyway, I initially asked the question since my TV's speakers are of ass quality and my computer speakers, although 10+ years old deliver brilliant sound...wish they looked new though. They are Yamaha speakers.
I personally think M$ kind of did a cheap trick there...making you buy THEIR HDMI cable if you wanted to use an audio system. I mean I can use the "audio out" ports on my TV but I tested that today and they deliver a nasty "hiss" like no tomorrow and that gets annoying when no sound (besides the hiss) are being emitted from the speakers...
As a fighting games fan I thought it was bad enough they designed the shittiest directional pad on the face of the Earth...but now they make FAT COMPOSITE/COMPONENT/VGA cables to block out HDMI cables that are not made by them.
