Testing
To test Icecast:
|
|---|
cd liquidsoap/src
./liquidsoap 'output.icecast(%vorbis, mount="test.ogg", sine())'
mplayer http://localhost:8000/test.ogg
|
To test direct soundcard output:
|
|---|
cd liquidsoap/src
./liquidsoap 'output.ao(sine())'
|
In both of the options above, you should hear a constant buzzing noise that is generated by the input sine wave.
