I've got an Airtime 2.1.2 installation, on Ubuntu 10.04.
Several times a day, the audio output gets caught in an endless loop, stuttering the same 40ms frame of audio endlessly, over and over again, like a CD skipping.
This is with an hda-intel soundcard, using ALSA output. There are no icecast streams, just audio card output. CPU usage is trivial during the times when this happens, like 3% or so.
I should also note, that when this is happening, there's nothing odd in the airtime logs, no underruns, and nothing in /var/log/messages either. There seems to be no way to tell remotely that there's a problem, except you sure can hear it if you're there!
Restarting the playout engine "solves" the problem. But then it chokes again some 5-10 hours later. This is obviously unacceptable for an unattended station.
What is going on? How can I stop it from doing this?
