Audio doesn't work in packaged project

I packaged the project and sent it to a couple of friends, when they try the run the game, they got no audio. Everyone who’s tried my project has had the same issue, but when I run the application on my machine, it works fine. Attached below is the error one of my friends got when running the game.

Hey @Bladeworkzgames!

It looks like they need to update their DirectX package! It’s a normal part of Windows, and is usually packaged alongside games since the 90’s, especially since back then internet access wasn’t so widespread. Send them to this link and have them update!

So, they tried that, but it said that their directx was already up to date. And after that they tried the game and the audio still wasn’t working.
