+To enable S/PDIF funtionality ``XUA_SPDIF_TX_EN`` must be set to a non-zero value. Setting this will cause the ``XUA_AudioHub``
+tasks to forward samples and sample rate information to the S/PDIF transmitter task. 
 
 These parameters are set via defines in an optional ``xua_conf.h`` header file. For this simple application the
