I have the following problem. We use vMix and want to show a video on the speaker's laptop. The video including sound should then be streamed with vMix via Zoom. The laptop is connected via HDMI to a Birddog Mini, which we have as NDI input in vMix. The video signal is captured without any problems, but no sound is transmitted. The Birddog mini is selected as the audio output on the speaker's laptop. Does anyone have any advice on how we can solve this problem? Is there a setting in vMix that we need to adjust?
