| 59 | ----------- |
| 60 | |
| 61 | This ioctl call asks the Audio Device to bypass the Audio decoder and |
| 62 | forward the stream without decoding. This mode shall be used if streams |
| 63 | that can’t be handled by the DVB system shall be decoded. Dolby |
| 64 | DigitalTM streams are automatically forwarded by the DVB subsystem if |
| 65 | the hardware can handle it. |
| 66 | |

| 68 | RETURN VALUE |

| 70 | |
| 71 | On success 0 is returned, on error -1 and the ``errno`` variable is set |
| 72 | appropriately. The generic error codes are described at the |
| 73 | :ref:`Generic Error Codes <gen-errors>` chapter. |
