If you have a standalone microphone (or a headset with mic), plug it to your PC and launch the game again to see if that helps. actually, it doesn't have to be a real microphone a cheap pair of earphones should also work, as long as it's plugged to mic port. If you had no luck with stereo mix even when your audio driver was updated, then consider plugging something else to mic port (must be located in front of case and on motherboard). you may need to update your audio drivers if stereo mix isn't available there, but it's still possible that even modern drivers could not support it for your motherboard (typical case for most windows 10 systems). If you don't have any sound input device, then you need to enable "stereo mix" at windows sound settings (it's shown in the video below, between 0:50-2:00). that's the usual fix for many players, as CoD4's multiplayer apparently tries to find a sound input device while starting, and crashes soon if it can't detect one (the same issue can occur in CoD2 MP as well, just fyi). If you have a standalone microphone (or a headset with mic), connect it to your PC, then launch the game again to see if that helps. Either loading it through the main menu or through the.
