    Hello,
    I'm trying to configure Liquidsoap to play music when nothing is sheduled on airtime.
    But i don't understand, i can have noise and sine, but when i want to play a song or a playlist, liquidsoap is off...

    Do you have an idea of the problem ?

    I've just changed this :

    default = amplify(0.00001, noise())
    default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)

    into this

    default = playlist(mode='random', "/home/unilinux/bureau/music/")

    Liquidoap work for airtime, noise, sin etc... 
    but not when i want to play a song.

    Icecast work with noise, etc... but not when it's a song...

    Error from files permissions ?

    Is it an error from codecs ?

    Hi Romain,

    That error is happening because port 1234 is not available on your machine. I'm assuming airtime is running on your machine, so LS that is running with airtime is already using port 1234 and your command line LS is trying to get that port again. That's why you see the error msg.

    For your original problem, what do you mean by LS is off? how did you confirm it is actually off?

    Thank you.

    Thanks James,

    When there is default = amplify(0.9, noise()). I can hear the noise, airtime works, and listeners can listen the Icecast server.

    When there is :

    default = playlist(mode='random', "/srv/music/")

    I can't hear music and listeners can't listen the Icecast server, however they can listen when it play sheduled playlists with Airtime.

    The directory is good, but I hear no sound... Is it necessary to have specious permissions on the directory ?

    If you can help me, thanks !! It could be urgent ;) (it is...)

    Thx 
    Romain.
