Picotts + vlc no output

Configuration
1

Hello,

I’m trying to setup a local audio output on my pi3. After reading a bunch of threads, I went with vlc-nox and picotts but I’m stuck with no sound from HA.
Running 0.37.1 AIO installer, I have this in my config:

tts:
  - platform: picotts
    language: 'fr-FR'

media_player:
  - platform: kodi
    host: yoda
    name: Kodi
    username: xbmc
    password: !secret xbmc_password
  - platform: vlc
    name: vlc

in my script yaml:

test_vlc:
  sequence:
    - service: tts.picotts_say
      entity_id: media_player.vlc
      data:
        message: 'Que la force soit avec toi.'
test_kodi:
  sequence:
    - service: tts.picotts_say
      entity_id: media_player.kodi
      data:
        message: 'Que la force soit avec toi.'

Test_kodi is working well. Test_vlc is not playing.
After different things, I can say:

  • wav file is created in /.homeassistant/tts

  • wav file can be played in command line with pi user

  • wav file can’t be played in command line with homeassistant user:

    pi@pi:/home/homeassistant/.homeassistant/tts $ sudo su -s /bin/bash homeassistant
    homeassistant@pi:~/.homeassistant/tts$ ls
    c6832f313b8a4fd38a2f0ee1eb91a13a59d4249e_fr-fr_-picotts.wav
    homeassistant@pi:~/.homeassistant/tts$ vlc c6832f313b8a4fd38a2f0ee1eb91a13a59d4249e_fr-fr    -_picotts.wav

I’m not sure what or where to look at.

Thx for any advice.

What audio device are you trying to get output from also what does

aplay -list_devices

output. And last but not least did you add homeassistant to the audio group?

The audio group did the trick. Thank you very much.

Thanks so much.
Is there other tricks to have a correct volume ?

I think you can set the volume from the frontend?
