No supported XAudio2 library found

I have seen this a few times before and sorry but I have no idea why it is happening. I thought of something, try running the (cmd) command

Code:

regsvr32 filname.dll

and replace filename with the name(s) of the Xaudio .dll file(s).

Hey, I have exactly this same issue. I'm also using Windows 7, you can see my rig in my signature.

This is my first time trying RPCS3 and this is the only emulator that is having issue so far with the Xaudio2, every other emulator like Cemu, PCSX2, Dolphin, etc... work just fine, I don't know why this emulator is having this type of issue, the drivers, distributable files and the Xaudio are up to date.

Just in case, should I need to type regsvr32 XAudio2_0.dll in the command line on all those files? I have plenty of Xaudio2.dll files, from XAudio2_0.dll through XAudio2_7.dll, so should I type that in the command line on all those 7 Xaudio2.dll files?

Honestly, typing that on all those .dll makes me a bit nervous, I don't know if that will affect the other emulators.

Edit 1:
BTW, I tried 2 games so far: Catherine and Metal Slug 3. I have the Xaudio2 issue everytime I start the game with Xaudio2 selected in the emulator, however, if I change the audio output to Null or OpenAL then Metal Slug 3 start working but Catherine keep having the same Xaudio2 issue and does not work.

Edit 2:
Got Catherine to work by changing the audio output to Null or OpenAL by right clicking the game and selecting Configure, Xaudio2 is the one that is not working for now. Changing the audio output globally didn't work for this one, it needed to be changed by right clicking the game. Any help is appreciated.
