No engine sound for certain mods and cars? Need help please

[shaun_ccxr]

I'm sure this has been asked before but i can't seem to find the solution.

I usually plus BES 2012 mod without any problem and recently i downloaded the shift street mode just for fun, the original cars included in the mod works great but also added a few DLC add ons cars such as the SLR 722 and Enzo, the cars and physics works fine but theres no sound at all. checked its not the mod or sounding problem, just specifically these 2 cars.

I found out that the sound file name of the Enzo is MC12_Maserati does that cause the problem or its something else?

thanks
