I purchased the xbox last sunday, and it is an excellent system. I also bought Halo, and the system rocks with my home theater setup! However, it seems that I'm having a problem with Halo. Is anybody getting audio hissing in the beginning scenes where you get out your capsule, and one of your crewmen is telling you what each button is used for, and also in scenes where Cortina is also talking to you. In those scenes, I'm hearing like static and hissing when their is speech. Is it supposed to be like that, or is my xbox defective? Please help because I'm starting to get paranoid over here!!! Thanks. Also, when I push my z and other trigger button on my controller, am I supposed to hear a sound such as a spring being released? When I hold it, and let it go, the "springy" sound is really apparent. Is it supposed to be like that? Thanks again.
