There is no sound
Note:
High-Bit-Rate audio formats such as Dolby True-HD or DTS-HD Master Audio
cannot be sent over the S/PDIF cable.
Check incoming audio
Start the controller software or the webpage and verify the incoming audio at the
input settings. If there is no audio on the input, you should try changing the
emulated EDID or review the settings of your source.
Check the outgoing format
Start the controller software or the webpage and verify the mode at the output
settings. If the port operates in DVI mode, you can try forcing HDMI operation.
Note:
The S/PDIF outputs work both in HDMI and in DVI modes.
Check the EDID
It is possible that your device doesn’t support the sent audio format. Try emulating
your display device’s EDID to the source. You will find help to this process on Page
36, Page 72 or Page 85. If you get a picture now, you have an EDID related issue,
please read the Advanced EDID Management chapter on Page 90.
