58 | DESCRIPTION |
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 | ||
67 | ||
68 | RETURN VALUE | |
47d23e36 MCC |
69 | ------------ |
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. |
