OK, so that’s your problem - because a “FramedSource” is not meant to be read by more than one downstream object at the same time.  (In fact, the code is supposed to trigger an internal error (and exit()) whenever this happens; I don’t know why you’re not seeing that.)

Your solution is to use the “StreamReplicator” class to create a separate “FramedSource” object from the original audio stream, and use that in your second “ServerMediaSubsession” - i.e.

If “audioSource” is your original audio “FramedSource”, then do:
	StreamReplicator* replicator = StreamReplicator::createNew(*env, audioSource);
	FramedSource* audioSource2 = replicator->createStreamReplica();
Then use “audioSource” in your first “ServerMediaSubsession”, and use “audioSource2” in your second “ServerMediaSubsession”.
