Test tones

If you need to test your computer's soundcard, you can use speaker-test, a tone generator for ALSA. This does not come installed with LibreTime but can be installed with sudo apt install speaker-test.

speaker-test [-D] [-f]

Where:
    -D device name
    -f frequency of test tone

The airtime-test-stream command enables you to send a test tone to a local or remote streaming media server. Press Ctrl+C on your keyboard to stop the tone being streamed.

airtime-test-stream [-v]
               [-o icecast | shoutcast ] [-H hostname] [-P port]
               [-u username] [-p password] [-m mount]
               [-h]
Where:
     -v verbose mode
     -o stream server type (default: icecast)
     -H hostname (default: localhost)
     -P port (default: 8000)
     -u user (default: source)
     -p password (default: hackme)
     -m mount (default: test)
     -h show help menu

RabbitMQ hostname changes

If the Airtime logs indicate failures to connect to the RabbitMQ server, such as:

2013-10-31 08:21:11,255 ERROR - [pypomessagehandler.py : main() : line
99] - Error connecting to RabbitMQ Server. Trying again in few seconds

2013-10-31 08:21:11,255 ERROR - \[pypomessagehandler.py : main() : line 99\] - Error connecting to RabbitMQ Server. Trying again in few seconds - See more at: http://forum.sourcefabric.org/discussion/16050/\#sthash.W8OJrNFm.dpuf

but the RabbitMQ server is running normally, this error might be due to a change in the server's hostname since Libretime installation. Directory names under /var/lib/rabbitmq/mnesia/ indicate that RabbitMQ's database files are organised according to the hostname of the server (ex. rabbit@airtime) where the hostname is airtime.example.com. If the hostname has changed, it may be necessary to reconfigure RabbitMQ manually, as follows:

1. Delete the files in /var/lib/rabbitmq/mnesia/

sudo rm -r /var/lib/rabbitmq/mnesia/*

2. Restart RabbitMQ:

sudo systemctl restart rabbitmq-server

3. Enter the following commands to set up authentication and grant permissions. The rabbitmqctl add_user command requires the RabbitMQ password from the /etc/airtime/airtime.conf file as an argument. The rabbitmqctl set_permissions command should be entered on one line, with the list of Airtime services repeated three times:

rabbitmqctl add_vhost /airtime
rabbitmqctl add_user airtime XXXXXXXXXXXXXXXXXXXX
rabbitmqctl set_permissions -p /airtime airtime
   "airtime-pypo|pypo-fetch|airtime-analyzer|media-monitor"
   "airtime-pypo|pypo-fetch|airtime-analyzer|media-monitor"
   "airtime-pypo|pypo-fetch|airtime-analyzer|media-monitor"
