I have not played the F1 2010 in sometime now but I decided to give it a try yesterday only to find I have no engine sounds. I did check the hardware settings in the config file and that is set properly with it set [FONT="]audio mixing="software" reverbs="0" voices="100"[/FONT]. Also Blue Ripple is in my start menu. I did install the Shift II Unleashed since I played F1 last. Could that have anything to do with it?
