For those of you that are having sound issues with the 360 version of crysis3 this is what i did and it seems to have worked 100%. go into SYSTEM/CONSOLE SETTINGS/AUDIO/DIGITAL OUTPUT,once there select digital stereo. i went back to mission 2 where i had virtually a total loss of sound and replayed the level no sound break ups whatsoever it must be an issue with the 5.1 audio track try it and let me know what you think oh and wether it matters or not i installed the game to hdd
