Using audio from captured HDMI signal
-
Hi, is there any way to pass the audio received on a Decklink Duo 2 from a laptop via HDMI? The meters on the preview show there is signal present, and in fact I can output the audio if enabling the "Hear this device" option on Windows sound setup, but I can't find any way to run the audio signal thru Isadora so it's only active on scenes where I use the video input. Is there any actor or plugin I'm missing that does that?

Hello!
Not quite sure what you want to achieve. You want to hear the audio from the laptop only when there's video? Or what, exactly?
When you say "The meters on the preview show there is signal present" do you mean the ones in the Live Capture Setting window?
Anyhow, you can use the capture control actors to determine what and when you want to capture. Here's the help from that actor:ACTOR HELP: Capture Control (This page was automatically generated from the actor's built-in help text.) OVERVIEW Starts or stops capturing video and/or audio INPUTS channel (Integer) The live capture channel that will be affected when this actor is triggered, as specified in the Live Capture Settings window. function (Integer: [Property Defined]) Determines whether capturing will be started or stopped, and the video/audio capture mode.'vid+aud' starts capturing both video and audio, 'vid' starts capturing video only, and 'aud' starts capturing audio only. To stop capturing, choose 'none'. size (Integer: [Property Defined]) Selects the size of the capture. Use 'default' to use the setting in the Live Capture Settings window. Otherwise, select the desired resolution for the live video input. (This setting has no effect if not capturing video. trigger (Trigger) When triggered, starts or stops capturing video and/or audio, based on the setting of the 'function' parameter.
Does this make sense? Basically you use the Capture Control actor (maybe with an enter scene trigger) to determine what you want to capture - video, audio, or both - at any given time.
Maybe the word 'capture' is a bit misleading, but I use this actor all the time to start and stop live camera capture so the live cameras are only working when I need them to.Hope it helps!
