I looked at the code and it looks fine actually. Could it be any of these?
- call gets disconnected?
- something disconnects your port from the bridge?
- something in your callbacks blocks the program (e.g. mutex)?
- something stops the sound device from calling the callbacks (try
with --null-audio instead)
- ... ?
