Even with the LLE audio? Hmm...the first thing that comes to mind is the cheats aren't compatible with your game for some reason. Try calculating the MD5 checksum (right click on the game in the Dolphin menu, go to properties, go to Info, calc MD5) and see if it matches this:
MD5=09a28c6fc53435b2d478516aac50055c
MD5=09a28c6fc53435b2d478516aac50055c
