+Description
+-----------
+
+This ioctl is obsolete. Do not use in new drivers. It has been replaced
+by the V4L2 ``V4L2_CID_MPEG_AUDIO_DEC_MULTILINGUAL_PLAYBACK`` control
+for MPEG decoders controlled through V4L2.
+
+This ioctl call asks the Audio Device to select the requested channel
+for bilingual streams if possible.
+
+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.
