Audio underbed playback
Using Wirecast 9, on my Windows 10 desktop, I've setup my video and audio input (BMD Decklink) on Layer 4 which works fine. I place an audio only file on Layer 1 and lower the volume to play underneath Layer 4. Wirecast is setup with a Preview/Program switch and for media to autoplay when sent to program. When I test it I can hear the audio playing underneath. During production (recording and streaming), however, I put Layer 4 active in preview (on top of my Layer 1) set it to active and the Layer 4 music doesn't play. I try to start it in preview and then send to program and it doesn't play. What could be the problem?
