+Description
+-----------
+
+This ioctl is for Digital TV devices only. To control a V4L2 decoder use the
+V4L2 :ref:`VIDIOC_DECODER_CMD` with the
+``V4L2_DEC_CMD_START_MUTE_AUDIO`` flag instead.
+
+This ioctl call asks the audio device to mute the stream that is
+currently being played.
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
