+Description
+-----------
+
+This ioctl call asks the Audio Device to bypass the Audio decoder and
+forward the stream without decoding. This mode shall be used if streams
+that can’t be handled by the Digial TV system shall be decoded. Dolby
+DigitalTM streams are automatically forwarded by the Digital TV subsystem if
+the hardware can handle it.
+
+
+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.
