Airtime appears to be On Air (image has a red background) when the scheduled playlist is in the right time slot, but in the System->Stream Settings I see an error message: Can not connect to the streaming server 'bad answer'. The listen2myradio server is Shoutcast 1 so I set up the stream type as mp3/128kbits. The server address and port are correct and I set my password in the Additional Options. I'm using Airtime 2.0.2 on an Ubuntu 10.04 server.
I know that Liquidsoap can stream to the server because I have run it from the command line feeding it my own .liq script. I don't know enough about the Airtime internals to guess which script it is feeding to Liquidsoap. I examined the liquidsoap log (sudo airtime-log -v liquidsoap) and found the following relevant entries:
2012/03/24 10:20:17 [shoutcast_stream_1:3] Connecting mount / for source@'my radio's IP'...
2012/03/24 10:20:18 [shoutcast_stream_1:2] Connection failed: bad answer
Then pypo sends a notification about the 'bad answer', liquidsoap attempts to reconnect (in 5 seconds) and the process repeats indefinitely.
I am listening to the stream now (using the command line to run liquidsoap with my .liq script), but I would love to use Airtime because of the scheduler and flexibility in using multiple playlists.
