Liquidsoap fails with ALSA (Airtime 2.3 and Ubuntu 12.10)

    I'm finally upgrading Airtime to the latest version and have a fresh install of ubuntu Server 12.10 to use as a test machine. Airtime installs fine and running airtime-check-system immediately after the installation checks out. The problems begin once I login and change the output to "Hardware Output". Running airtime-check-system again shows that Liquidsoap has failed:

    What's the output of

    sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap

    ?

    It's the last paragraph above. Simply that banner message.

    I see, I will need you to do the following:

    open 
    /usr/lib/airtime/pypo/bin/airtime-liquidsoap

    and change line

    ls_path="/usr/bin/airtime-liquidsoap --verbose -f -d"

    to

    ls_path="/usr/bin/airtime-liquidsoap --verbose -f"

    (simply remove the -d). Then run

    sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap

    again

    It looks like you are using PulseAudio. If you are running a server, I believe PulseAudio is not included by default. Either install the pulseaudio packages, or switch to ALSA.

    That's odd as I don't have Pulse installed, just ALSA and the top line of the config file (and the Airtime GUI) is set to ALSA

    Hmm, it may be that if the Liquidsoap binary has been compiled with PulseAudio support, and you attempt to use ALSA, it will still attempt to use ALSA, but may error out before that point simply because it may have checked if PulseAudio was available.

    If this is the case, we have two options. Either compile your own Liquidsoap binary, or use the existing Liquidsoap binary and install the PulseAudio packages.

    That'll probably work but I think we're putting the cart before the horse. This is a completely clean install of both the OS and Airtime, we shouldn't have to be installing Pulse if ALSA is installed and I can access the soundcard fine:

    card 0: PCH [HDA Intel PCH], device 0: CONEXANT Analog [CONEXANT Analog]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
      Subdevices: 1/1
      Subdevice #0: subdevice #0

    Airtime-Test-Soundcard:

    airtime-test-soundcard
    Sound API: alsa
    Outputting to soundcard. You should be able to hear a monotonous tone. Press ctrl-c to quit.
    There was an error using the selected sound API. Please select a different API and run this program again. Use the -h option for help

    Hey,

    What I was trying to say is that if Liquidsoap was compiled with pulseaudio headers, then it most likely expects the pulseaudio library to exist on the system it runs on.

    So installing the pulseaudio packages is just a suggestion, but the best way would be to recompile liquidsoap without pulseaudio support.

    Sorry I didn't mean to be quite so rude! Hmm I just installed Airtime using apt-get is the shall I try and install the Liquidsoap package from your own repos?

    The Liquidsoap binary you have is most likely provided by our own repos. You can verify by doing "dpkg -l | grep liq" and check if there is an "sfo" in the output version string.

    Building the Liquidsoap binary yourself is easy (and detailed instructions are here), however I'll get back to you if there's an easier way around your current situation

    Why do you think this has happened? I've installed Airtime smoothly enough before on several machines. Do you think it could be some kind of error thrown up by the sound card itself? 

    Doesn't like like I am using the Sourcefabric ones:

    That error trace you see has been fixed in 2.4 but is harmless. Is
    Liquidsoap working now?

    I'm afraid not. I compiled the binaries as per your instructions and now on a whim have tried re-installing on Ubuntu 12.04. Same issue. Do you think it's related to using an Intel HDA based sound card?

    I had the same problema and I just had to install liquidsoap-plugin-alsa

    apt-get install liquidsoap-plugin-alsa
