49 | ----------- |
| 50 | ||
| 51 | This ioctl call asks the Audio Device to bypass the Audio decoder and | |
| 52 | forward the stream without decoding. This mode shall be used if streams | |
| 53 | that can’t be handled by the DVB system shall be decoded. Dolby | |
| 54 | DigitalTM streams are automatically forwarded by the DVB subsystem if | |
| 55 | the hardware can handle it. | |

59 | ------------ |
| 60 | ||
| 61 | On success 0 is returned, on error -1 and the ``errno`` variable is set | |
| 62 | appropriately. The generic error codes are described at the | |
| 63 | :ref:`Generic Error Codes <gen-errors>` chapter. |
