Hi. I have this trouble what for Windows7 works only OpenAL plugin. If i uses Xaudio2 then RPCS3 write log "No supported XAudio2 library found" 
Sound driver updated
DirectX updated
I tried directly put xaudio dlls to path Windows/system32, RPCS3 but this no effect
p.s. For Windows10 works OpenAL and Xaudio2 both
