Hi: I'm learning to record from the nintendo switch. The instructions of my Kedo capture card says to use OBS and in the video source window configure audio as follows: "Audio Output Mode" to "Output desktop audio (WaveOut)", then click "Use custom audio device". When I click that box I loose my video. When I unclick it, I get my video back. Can you please help me understand why I loose my video when I click on "Use custom audio device"?
