Flow Chart 4: No Audio
What to Expect with Normal Audio
The normal display for the Audio LED (and Video LED) at power up when an audio signal is present is:
the LED illuminates, turns off, and then illuminates again as the audio is heard at the destination.
Important:
Video must be present or audio cannot be transmitted.

Source Device
> Verify that the source device is sending
a valid audio signal by cabling directly to
a destination known to be operational.
> Check that the audio sample rate is
supported (32 k, 44.1 k, 48 k, 96 k).
> Check that the audio sample rate is not
out of spec for the video signal (if using
96 k for PCM digital audio then the pixel
clock must be at least 40 MHz or a video
format of at least 800x600 @ 60 Hz).
> Check that the audio signal is not
compressed (e.g., Dolby).
Destination Device
Check to be sure destination
device supports the audio.
Yes
Finished
* Assumes the modules are
receiving power and a video signal
(if video is not present, audio
cannot be transmitted).
Contact technical support (page 64).
Important:
The Power LED can
illuminate solid amber at any time,
not just at power up. If this occurs,
check the error code (see page 62)
and contact technical support.
Note:
Normally on power up, all LEDs
turn on, turn off, and then illuminate in
their operational state.
