AlexaPi service not starting

So a friend helped me get Pulseaudio configured and running yesterday. Everything was working fine. Now I tried to get AlexaPi working and I thought that'd be a walk in the park since I hade Alexa-acv-sample-app installed and working before. I followed the guide in "Audio-setup-&-debugging" and now I have no sound at all on my system, no input or output is working anywhere. VLC seems to be completely broken as well and I don't know if that's a separate issue or not. Here's what I get from the log:

sudo systemctl status AlexaPi.service

Do anyone have any ideas why it refuses to start AlexaPi or recognize my voice input or output?
