With regard to driver issue, yes u are right, when it close , it doesnt clear up the driver and shutdown it even if I called VoiceCapture->Shutdown() , I have checked this error on stackover flow .
For .xml , I think I can dig there, but not sure exactly where to find the file , I will search for it ,but yes, I’m struggle as hell ,its like 1 month for now even more . and really I dont wanna move to unity cuz of this, since my app depends on this feature mainly ,even unity has more worse bugs related to some devices gpus already and they didnt fix it as they told me “Out datated gpus” while I’m still able to hit 60fps with unreal with decent scenes on my current device .
anyway, if u are able to get any fix let me know, while I keep digging hard already, and if I could hit the fix, I will update all of my thread related to that.
Thanks again mate:))
