AUDIN_FORMAT
Selects the audio input source that will
be embedded on the HDMI signal
through the Transmitter.
Note:
When the Transmitter is set to
route digital video (input 7), you can
select from the HDMI, SPDIF, or
ANALOG audio inputs. When the
Transmitter is set to route analog video
(input 8), you can only select the
SPDIF or ANALOG audio input (see
the VI<input>O<output> command
on page 71.
Syntax:
SEND_COMMAND <DEV>,"'AUDIN_FORMAT-<format>'"
Valid responses:
format = HDMI, SPDIF, ANALOG
Example:
SEND_COMMAND dvTX,"'AUDIN_FORMAT-ANALOG'"
Important:
The order of precedence (HDMI embedded audio, S/PDIF,
analog) can be overridden with this command; however, you must first send
AUDIN_FORMAT_AUTO-DISABLE
to disable the auto format function, or the
audio format will automatically switch back anytime the order of precedence is
violated.
