Earlier I had no problems running my XBOX 360 Elite via HDMI. Now I have moved and must have lost some settings because when I first connected the XBOX to my TV I had no sound via HDMI.
I called support who adviced I could turn off Display Discovery. This got the sound back in the XBOX-menus, games seems ok etc. However, when I want to play a DVD, the sound start hacking/buzzing very loudly all the time. Same thing if I manually change audio settings from Digital Stereo to Dolby Digital 5.1, then sound immidiately start hacking in the XBOX-menu as well.
Any advice would be much appreciated.
