Hey i have the same problem i don't know when the silence started but while i was sleeping and when woke up the tracks where playing but no sound output...
this is currently happening to me too. I've no log handy at the moment but I do know that it started almost immediately after I downloaded a file from our library onto a remote computer. Airtime seemed to stall for a few moments when I hit download and afterwards audio was silent. Everything appears as normal. I'll post logs when in studio tomorrow.
Is this still happening? If you can still reproduce this, please post the log file again, what time the audio failed, and also a copy of /var/log/airtime/pypo/pypo.log
Well i got another server ubuntu 11.10 and i never had any silence just sometimes songs playing twice(this just happened) because of the cue in/cue out its either airtime or the song duration ? I noticed sometimes the now play song metadata in airtime/in my player lags behind... its a whole new song but i see the old one.
I was using smart_crossfade maybe that's why the songs lags behind.
