|the problem is likely either with the game installation or your audio drivers.|
1) is this a legitimate copy of the game that you paid money for? Because if you downloaded the game illegally without paying for it, it's probably just a bad copy and no one here can help you (or wants to, you damn dirty pirate).
2) do a complete uninstall of the game, then run a reg cleaner like CCleaner, then try reinstalling again.
3) update/reinstall your audio drivers.
