Audio Problems
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 is still 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.
Possible Solutions
If you encounter audio problems, we recommend trying these solutions:
Use the EDID programming functionality in the DGX Configuration Software
(see page 166) to read the EDID from the destination device (see page 168) and to write
it to the HDMI input on the Enova DGX Switcher (see page 170).
Use DGX Configuration Software to write an EDID to the HDMI input on the
Enova DGX Switcher that best represents the downstream destination. Check the
AutoPatch_EDID_Library file at www.amx.com (search for EDID Library) to determine if
one of the custom EDID files meets your needs. (The custom EDID files are variants of base
EDIDs.) For additional information on custom EDID files, see page 170.
