It sometimes can not capture audio, pData is ''

When start play, sometimes it can not capture audio data , pData is '', and BP_methods return empty TArray.
Though, it usually happens when PIE from 2nd times on. some times It can capture audio when first time PIE after open project luckily, more often It didn't capture data never after open project.

I think it need some sorts of 'clean up' for 'windows audio core utilities'.

Ok I see it by default captures output device, not microphone, not a issue.
