TRUE: Bypass is disabled
FALSE: Bypass is enabled
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 cant be handled by the Digial 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.
