This method is typically called by an AlsaTransmitter that got an AlsaReceiver as its Receiver.

Parameters:

nClient - The ALSA client number of the Transmitter that a read subscription should established to.

nPort - The ALSA port number of the Transmitter that a read subscription should established to.

Returns:

true, if the subscription was established, false otherwise.
