Audio capture feature in LocatableCamPlugin?

[kubas1129]

Hi,
I'm struggling with an audio capture in Hololens 2 for a quite time, and after digging into this topic I found out that, in a LocatableCamPlugin there is a possibility to change StreamingCaptureMode to AudioAndVideo and receive MediaFrameSourceKind::Audio, but I stucked on implementation of grabbing an audio sample in async operation. Would anyone trying to acomplish this or can point out a way to handle with it?

Thanks!
