I set the latest version of libretime to the ubuntu20 version.

I think I’ve done all the settings, but the audio output through the hardware (3.5Jack on the audio card) is not running.

/etc/libretime/config.yml at the bottom

```yml
# # System outputs.
# # > max items is 1
system:
- - # Whether the output is enabled.
# # > default is false
enabled: false
# # System output kind.
# # > must be one of (alsa, ao, oss, portaudio, pulseaudio)
# # > default is alsa
kind: alsa

```

I changed enabled: false to enabled: true.  
The red light turns off at the on air at the top of the libretime.  
The icecast connection was also disconnected at the same time.

Sure. I already added it to the group using the command below.

sudo adduser libretime audio
