How to get audio to go through USB speaker

Hello! I’ve been messing with my Mycroft running on a Raspberry Pie 3 for a while and I can not get the audio to go out of the USB speakers. I chose the USB speakers option and I’ve done the troubleshooting directly from the Mycroft support website. Any help?

Can you detail what steps you’ve taken, and what the results of that were? Can you provide more info like the pulse ids and volume settings and such?
