Hi,
I'm experiencing an issue identical to the one described here:
http://sourceforge.net/mailarchive/forum.php?thread_name=154311232599096%40webmail87.yandex.ru&forum_name=savonet-users
In short: after some time (several hours or a few days) the output from
LiquidSoap is muted. Everything appears to work properly i.e. metadata
is updated, logs indicate that LiquidSoap is operating as it should but
listeners can hear nothing but silence. As far as I noticed the problem
occurs in a middle of a song and not during song change.
I'm using version 0.3.8.1 installed from a binary package for Debian
4.0. Below is the script I use. In order to find the source of the
problem I eliminated amplify(), smart_crossfade(), transitions in the
last instance of fallback() but that didn't help.
I've noticed that if I start harbor input (called live in the script)
LiquidSoap properly switches to it and sound can be heard. After harbor
input terminates the script properly switches to the previous playlist
and continues to operate properly for some time.
I'm about to move LiquidSoap to a different server. Then I will be able
to leave LiquidSoap in this muted state and give you access to the logs.
I hope this will allow you to find a solution.
Regards,
