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