Has anyone been able to get any audio out of the "Blackmagic WDM Capture" audio stream (stream 1)?
I've got video working but every time I add audio (or audio only) the data stops flowing.

I have also in trouble in the same phenomenon at DeckLink SDI and UltraStudio SDI.
All durations of audio frame which recieved from Blackmagic WDM Capture Driver through Media Foundation Source , are wrong for the overflow with 100 ns units by 32-bit, to be calculated in 64-bit such as MFTIME types.
I suspect that there is a cause to the WDM driver or media Foundation source in DesktopVideo.
