Has anyone used VMix to record audio from FL Studio

Hi folks,

I'm trying to use the VMix software to record FL Studio video and audio to record for YouTube.

I use FL Studio ASIO output to a Focusrite USB sound "card". The Focusrite has my microphone attached for recording.

I'm able to record my voice with the microphone through the Focusrite with VMix, but I can't for the life of my figure out how to capture the FL Studio audio out. I can add FL Studio ASIO (I've tried ASIO4all also) as an audio input in VMix, but I don't get any sound.

If anyone else has used VMix, or knows some better software to capture FL audio, I would appreciate the input. I know some use an external hardware solution (mixing the audio out of the sound card back into the mike input), but I prefer to do it without hardware if possible.

Thanks for reading!
