Airtime

The main stream doesn't output sound

It happens sometimes, to repair it, you can send a master source with a streaming software and then disconnect it, the sound reappear ! ...

Airtime doesn't seems to play sound, show the media builder or eat new sounds

The 3 magic command to restart everything (you have to be logged in omnious :

sudo service airtime-media-monitor restart
sudo service airtime-liquidsoap restart
sudo service airtime-playout restart

also, see the logs in /var/log/airtime/
