have you tried patching it?
Sorry about the delay in getting back to you on that one. I've tried looking for a patch for it, but I'm not getting any specific to Windows 7 64 bit.
I tried the EA forums, but I'm still not seeing a cotton-pickin' thing. If you should happen to find one that may fix the sound issue in W7 then please do enlighten me, whereupon all your reward is likely to be is being showered with undying gratitude.
