There's multiple options:
- Use VAC and the microphone input
- Use VAC and then add the virtual input as a "file" to your queue/playlist and move it to a deck
- Use VAC and change the encoder source from DSP to record from soundcard (pick the right input device or make it your primary recording device in Windows)
- Don't use VAC and instead use the "What you hear"/Stereo Mix input with either of the 3 options above (mic input, queue/playlist file, encoder source)
Don't pick option 4 unless you're very sure you want have any unwanted sounds playing as that will really mirror the output of your soundcard as an input channel.
Thank you as always Benedikt for your helpful response. I will give it a shot. Much appreciated. - Mike
