Yeah I know there is a Forza 3 thread already but it's huge... I am running my 360 via HDMI through my receiver and I get random cracking/popping sounds through my speakers while racing, it's random but it seems to happen a lot at split times. I bypassed my receiver and ran the HDMI straight to my TV and it's still there. I tired a different cable and it's still there. I uninstalled the main disc from the HDD and it 99% went away, it may still be there a tiny bit but it's so quiet I don't hear it unless I really concentrate on it. So, anyone else with this problem?
