I just plugged in my USB capture card and I'm not getting any audio. Not just can't hear it, nothing even appears in it's Audio Mixer slider. I tried putting it's Audio Output Mode to "Output desktop audi" and "Capture audio only", neither worked. I went to the Advanced Audio Properties and went through all the options, no change.
VLC can detect the audio, so it doesn't seem to be a problem with the capture card. I can hear it neither in my headset nor in the livestream, absolutely no audio.
What am I doing wrong?
