Request a way to perform audio output through hardware

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

# # 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.

Did you add the libretime unix user to the audio group ?

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

sudo adduser libretime audio
