Audio Troubleshooting
If the destination device does not output the audio or if the audio is distorted, it may indicate that the destination
device does not support all of the features in the default EDID (2 channel L-PCM audio) on the DGX HDMI
Board. Some sources choose what signal types (audio and video) they are sending to a destination based on the
destination's EDID.
If, after changing the EDID on the HDMI input, the audio remains distorted or is not present on the destination
device, then the device may not be capable of supporting the audio format you requested with the newly loaded
EDID setting.
Checking for Support
The easiest way to check whether or not a destination supports a source device's audio signal is to connect the
source directly to the destination.
For additional information and a table showing which types of audio the different types of boards support, see
page 73.
Note: The default EDID supports 2 channel L-PCM audio so that signals routed to SC Optical Output Boards
or being inserted onto or extracted from Audio Insert/Extract Board will work without needing to change the
EDID.

Device between HDMI Output Board and Monitor

Sometimes a device (e.g., a video processor) between a DGX HDMI Output Board and the destination monitor is
intentionally installed to alter the image scale. If that is not the case and you have image problems, you need to be
aware that the scaler override function is responding to the EDID from the extra device rather than from the
monitor. One possible solution is to use the DGX Configuration Software to read and save the EDID directly from
the monitor and then apply the override values to the output (directions follow).
To read EDID directly from monitor and apply override values to output:
1. Remove the device between the output and the monitor.
2. Connect the output directly to the monitor.
3. Install and open the DGX Configuration Software (see page 153).
4. Select the Scaler Override tab.
5. Under EDID Source, select the Enclosure and select the Output number connected to the desired destination
from the drop-down lists.
6. Click Refresh EDID.
7. From the File menu, select Save to File and save the settings to a file.
8. Replace the device between the output and the monitor.
9. From the File menu, select Open File and open the previously saved file.
10. Click Apply to transmit the settings in the file to the output. This action is temporary until the settings are
stored on the connector in Step 12. Otherwise, the settings last only until power is cycled. The display
re-syncs with the output.
11. Verify that the display is satisfactory before proceeding.
12. Click Save to store the currently displayed settings to the connector and persist them in memory.
(If the settings have been changed since clicking Apply, the newest settings will be saved.)
