I have managed to re ord the hdmi in with various devices including games console wii U running at 1080p and apple tv. The wii U console recording comes back downsampled which is fine but has no audio. Any other device including the apple tv just shows the video but no souncd/audio is recorded.

Is this expected functionality or driver issue or am image issue? Is it possible to record the audio from any device plugged into hdmi in slot?
