I purchased a new toshiba tv. I connected the tv up to my xbox. I receive an hdmi video picture but I don't have any sound. Possible problem? :confused:

audio over hdmi with the 360 works for many people, but isnt officially supported. have you tried selecting a different audio output in the dashboard?

you may end up running the RCA audio cables to the tv, this may cause you to be required to use vga or component for your 360 video connection, unless you have an audio receiver you can run the sound directly to.
