I first encountered the X3daudio1_7.dll is missing error after installing a new Game,the Game in Question was Fallout 4 but do understand that this can happen in any Game that you may choose to install on PC. So if you are in a situation that your Game on Launching is giving you this error and will not start then follow the tutorial here to get the issue solved in the shortest time possible.
X3daudio1_7.dll is missing
The error is caused because the x3daudio1_7.dll file is missing from the Game directory or Windows and basically the Game will not function properly without the file and the error will appear on-screen and will hamper you from starting or launching your Game.
