Re: [Savonet-users] no way to have a sound output of liquidsoap
|
From: Xavier Mouton-D. <xav...@gm...> - 2014-08-21 13:58:35
|
changed a little bit like this :
«
playlist = playlist(mode='random', "/discotheque/Albums")
radio = fallback([playlist ,sine(440.0,amplitude=0.02,duration=1.0) ])
# Et on envoie
output.alsa(device = "pcm.liquidsoap", radio)
»
I have the sine tone, so the problem is definitively on ogg playing.
I'll remove everything on liquidsoap, and install it by parts, only to have
ogg and flac decoders
alsa output
Perharps something is going wrong with ubuntu 14.4.1 server packages ?
