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 Digital TV system shall be decoded. Dolby
|
||
|
DigitalTM streams are automatically forwarded by the Digital TV 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.
