44 | ----------- |
| 45 | ||
| 46 | This ioctl is obsolete. Do not use in new drivers. It has been replaced | |
| 47 | by the V4L2 ``V4L2_CID_MPEG_AUDIO_DEC_MULTILINGUAL_PLAYBACK`` control | |
| 48 | for MPEG decoders controlled through V4L2. | |
| 49 | ||
| 50 | This ioctl call asks the Audio Device to select the requested channel | |
| 51 | for bilingual streams if possible. | |

| 59 | :ref:`Generic Error Codes <gen-errors>` chapter. |
