No supported XAudio2 library found

I had the same issue as OP: It turns out to be some kind of speaker issue. When using my monitors built-in speakers I got the Xaudio2 error even when I downloaded the redistro, but when I switched to a external speaker for my audio output, games would load fine. I hope this helps find a solution to this problem.

Can you please elaborate a bit more on that? do you mean you changed to an external speaker in the "Playback Devices" settings?

By the way, I'm using "Breakaway Audio Enhancer", that's an application that enhance the audio quality for everything in your PC, this includes games, music, movies, etc... this can be changed in the "Playback Devices" settings but even using the default audio driver the PC comes up with I still get the Xaudio2 issue.

I've read in Discord that some peoples fixed the Xaudio2 issue by updating their Windows, this makes sense to me and it would probably fix my issue because I hardly ever update it.

Edit:

I updated Windows and the Xaudio2 issue was fixed. If anyone else is having the issue then you know what to do, time to update.
