Audio only outputting 1 channel

Hello!
I have ALMOST everything working on my RPi (YAY!!!). I need to fix the audio output on my audio. I have a StarTech.com 7.1 USB Audio Adapter External Sound Card. I have that hooked up through USB. I have audio output set to 5.1. All the physical connections go into the receiver. The log is at http://paste.osmc.io/egusaxehac. Is there anything I’m missing?

Does anyone have any suggestions?
