I understand. We used SAM Broadcaster to source audio streams to
Icecast, Shoutcast, and Windows Media servers. I have had a situation
where the SAM process hung in such a way that the encoders were still
connected to the streaming servers, but no audio was being encoded on
them. It may be that I need to learn more about how the encoders work
in order to determine the presence/absence of audio data.
