Audio Setup problem for VLC and SoX - need advice

See original GitHub issue

Your OS (including version) where you are running AlexaPi:

Rapsbian

Your hardware platform and model you are running on:

Rasp pi 3+

Python release (python2 --version):

Python 2.7.13

Description of problem:

I have a problem with audio setup and don't know how to fix it.   
I have tried both vlc and sox and followed the instructions for [PulseAudio](https://github.com/alexa-pi/AlexaPi/wiki/Audio-setup-&-debugging).

With vlc:

[6c6004e0] pulse audio output error: PulseAudio server connection failure: Access denied
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Access denied

[6c6004e0] alsa audio output error: cannot open ALSA device "default": Connection refused
[6c6004e0] core audio output error: Audio output failed
[6c6004e0] core audio output error: The audio device "default" could not be used:
Connection refused.
[6c6004e0] core audio output error: module not functional
[73837a78] core decoder error: failed to create audio output


With sox:

 DEBUG: Error attempting play. sox FAIL formats: can't open output file `default': can not open audio device: Access denied

Same with pulseaudio / alsa

Expected:

Problem-relevant config.yaml entries:

sox
  input_device: "USB PnP Sound Device: Audio (plughw:1,0)"
  output: "pulseaudio"
  output_device: ""
  playback_handler: "sox"


vlc
  input_device: "USB PnP Sound Device: Audio (plughw:1,0)"
  output: "pulse"
  output_device: ""
  playback_handler: "vlc"

Steps to reproduce:

Clean install

Traceback (if applicable):

Had one last look at the documentation to see if I had missed anything.

If you are running the root override (like on a CHIP or Orange Pi), you also need to add the user root into the pulse-access group: sudo adduser root pulse-access

Ignored it the first time, because I didn’t think is was required…

That seems to have done the trick!
