alexa snap fails to establish listening port
Using alexa (beta) 1.1 from 'data-art' on Ubuntu 17.04 x86_64.
Using these snap install instructions, I received an info message during install, and saw no listening port 3000 subsequent to the install. I'm quite new at snap usage, so this may be an error on my part.

I have the same problem. Even when installing the old way without the snap, I still get "Could not create pulse audio output stream: No such device or address" when running python3 alexa.py.
Unfortunately, there isn't a whole lot of info on the nature of the problem. What address did the script try to access (so maybe I can try to access it from outside the application and see if that works)? Is it a permissions problem (running as root didn't help)?
