Monitoring computer audio and USB mic

[blufishmedia]

New to OBS. I am recording the computer audio and my external USB mic. I ran a test and both are recording fine. My only problem is, when monitoring, I can hear the computer audio in my headphones but not my USB mic. I'm sure there's a checkbox I have overlooked. Can anyone help?

On the Audio Mixer panel, click the gear icon on your USB Mic and choose Advanced Audio Properties. You need to change the setting for Audio Monitoring.
