My experience as been quite different; it involves using a TV as the monitor. I have had many e-mails attempting to find a solution to my problem. Although not yet fixed t has been passed to the developers, who hopefully, will find a solution.
I'm trying to get Debut to record video. Although I get the video I cannot get the audio. I've tried connecting the output with the input but still have no success. I'm using a smart Samson TV as a monitor and have the audio output connected to a hi-fi system via an optical cable. The speakers work during recording the video. I'm running win 8.1 and have an Acis motherboard with a realtek HD audio manager in which I can set the various input and output devices. The all test fine.
