<p>An interface that allows the connection manager to control the audio
stream.</p>
<p>This interface is generally not needed. In cases where the connection
manager handles the network communication and the media is transferred
from the client to the connection manager via shared memory, it can
sometimes be beneficial for the connection manager to be able to
control certain aspects of the audio stream.</p>
