    Hi guys,

    I've successfully installed Airtime (1.6.0) on a fresh 10.04 Ubuntu.
    I can access to the Backend and upload several files, schedule playlists, etc.. .
    The only problem came from the stream between Liquidsoap and Icecast (not a credentials problem).

    The logs looks fine for pypo-fetch & pypo-push.
    But for pypo-liquidsoap, it try to switch between silence everytime (also during a Show playlisted and showing details into the Backend)

    Here's an example of the logs :

    Any ideas ?
    Many thanks in advance for your support.

    Hi Thomas,

    the logs indicate there is a problem with ALSA audio output.

    Can you please try the following steps:

    uninstall pypo/liquidsoap (we will reinstall this later)

    run the following:

    cd ~/airtime/pypo/install && sudo python pypo-uninstall.py


    (just run pypo-install after to reverse this change)

    then

    cd ~/airtime/pypo/liquidsoap/ && liquidsoap 'out(sine())'


    After running the previous command you should be able to hear a monotonous tone.

    Hi Martin,

    thanks for your reply.
    I've installed Airtime on a Ubuntu server, so there's no soundcard.. Smile

    It's required to install Alsa & a soundcard ?

    Best,
    Thomas

    Hi Thomas,

    It is not necessary to have a soundcard, but by default Airtime tries to use it.

    I recommend you use the 1.6.1 release which fixes a few bugs and does not use ALSA by default (only provides web streaming).

    You can download it here:
