AlexaPi doesn't respond after TuneIn Radio playback started

In order to help troubleshooting, be sure to include the following information: Your OS (including version) where you are running AlexaPi: Linux adhassbian 4.9.35-v7+ #1014 Your hardware platform and model you are running on: Pi 2 Model B v1.1 1GB a21041 (Embest, China) Python release (python2 --version): Python 2.7.9 Description of problem: Alexa stop responding after TuneIn Radio SomaFM Groove salad playback started. Music is being played endlessly until I restart the service manually.

Expected: Ability to interact with Alexa and control playback

config.yaml

  input_device: ""
  playback_handler: "vlc"
  output: "alsa"
  output_device: "default"
  snowboy:
    enabled: true

Steps to reproduce:

1. Alexa, play SomaFM Groove salad

Additional info: I use development branch of AlexaPi (sudo git clone -b dev https://github.com/alexa-pi/AlexaPi.git) with pulseaudio service stopped. Only in this case Alexa works smoothly with my Onkyo AV receiver via HDMI as ALSA output. I tried to use pulse without success.
