No Sound w/Video

OS: Windows 10
Proc: i7 6700k
Video Card: EVGA nVidia 980ti
Memory: 32gb
Monitor Resolution: 1920x1080
Video Editor: Vegas Pro 13
Game Problem: No audio captured during video recording or during live streaming to twitch
Video Type: MP4
Webcam: Logitech HD Pro C920 (driver version: 13.80.853.0)
Action! Version: 2.2.1.0

Microphone Settings -> Audio Device -> C920
Record to separate track: false

Video Recording -> Microphone -> Always record


I've never been able to get this software to record audio and video simultaneously. All of my drivers are up to date and all of the settings indicate that audio should be recording, but it isn't.
I can record an audio track all by itself and the audio file is generated as it should be.
Tried multiple modes (gaming, full screen, etc) to no avail.
Any help would be appreciated.
