sorry this is late but skip to 5:26
if you don't watch the video here it is
so first you have to have your audio device (EZCAP usb audio device) to listen through your speakers for sound (have your earphones/headphones plugged in if your trying to record your microphone i'll explain the reason behind this )
so if your trying to record both your voice and microphone have the box next to microphone in the audio section at the bottom of the settings checked and have speakers checked as well then adjust the volumes for both of these so its acceptable where you hear game audio but its not over powering your voice
to get your settings to show up be under "Screen" because while under device whether your ezcap is in use or not it will not let you change the settings
i hope you understand this and that it works for you also it doesn't work sometimes you have to close out debut and unplug your ezcap plug it back in and it should work sometimes you might to unplug and plug it back up a couple times
