Im having cinematic sound distortion (missing sections) in CODMW3 single player campaigns, the game play itself is not affected.

I've tried everything possible to correct this problem, different systems, Windows7 64bit/32bit, drivers, reinstalled games download from steam, and

also copied over orginal steam game from older game pc. ext. ext.

I'm believeing it is a cinematic engine problem now, could this be? and please make a patch to fix, Or if anyone as any hints or tips, feel free

to pass on this way.
