How to add VLC into my Hassio?

I use command line
"sudo apt-get install vlc-nox",
“sudo usermod -a -G audio homeassistant”,
but no sudo with Hassio.
How to add VLC into my Hassio?

Hassio uses Alpine, so just apk add vlc should work.

I tried. no worked.

Curious about this too. Using the SSH addon for hassio, there’s no apt-get or usermod as far as I can tell. Has anyone successfully installed VLC with hassio?

It is not possible to install packages on Hass.io. You’ll need to create an add-on to run an application besides Home Assistant: https://home-assistant.io/developers/hassio/addon_development/

It is not possible to have applications interact directly with Home Assistant. You can have add-ons communicate via MQTT https://home-assistant.io/hassio/run_local/

it works on my pi 3B ,thanks

in ubuntu and other linux

the problem is alsa!! e.g. sudo apt-get install vlc-nox and alsa-utils in HAdocker
the alsa Mutes individual channels by default . use alsamixer to available sounds
