Hdmi is meant for sound and video, what most people (like myself) are having an issue with is their configuration. And the most common misconfigurations are:
1) xbox running hdmi to tv, then from tv to amp/receiver <-- i use these two words interchangably because not many people are running seperates... And if you are your probably not having these issues....
This is not going to get you dolby digital 5.1 to your receiver, no matter what your feeding into the tv, unless your tv has a pass through hdmi port, where-in the same signal passed to the tv is untouched/modified by the tv. Or is other-wise stated that your tv can pass dolby digital 5.1 out (not just accept it)
2) xbox running hdmi to hdmi capable amp, amp to tv (this was my case)
*important* there is a setting in every amp to tell your receiver what to pass to the hdmi out, it can either be video, sound or both (on sony receivers its called tv aka video, amp aka sound, tv+amp both). What happens is is that (and this is noted a few posts up, sorry i didnt get the user name before i posted this) the xbox negotiates with the devices, and its seeing the tv because its being passed audio. My tv doesn't accept 5.1!!! Only two channel via hdmi, so it picks the lowest common denominator. Why xbox does this must be the hdmi chip they use because my ps3 does not negotiate with my tv. Another symptom could be no sound at all from your receiver!!!!! This was the case with my cable box, so for those of you having an issue getting 5.1 from your hd receiver via hdmi, this is also the problem!!!! So what you need to do is find the setting in your receiver that shuts the passing of sound to your tv via hdmi.
This is the case for anyone whos using their receiver as their component switch (like myself as my tv only as one hdmi input). Plus i never use my speakers on my tv, i turned em off. For those of you who still wish to use their tv speakers and have the option of flippin on their receivers, you must use the optical cable to the receiver, or like i said before, have a tv that has a pass-through hdmi port.
I hope this helps, i wrote a nasty hate mail to ms right before i figured this out.....not to mention the time spent cussing out the xbox
