Enova Digital Media Switchers - Hardware Reference Manual
Down-mixed audio is not present or is intermittent with good video:
A signal containing both video and audio must have space for both signal portions. The audio signal portion lies in
the blanked portion of the video signal. High Bit Rate Audio (HBRA) requires a larger than normal space in the
blanked area of the signal. Video formats with reduced blanking normally provide enough space for audio
signals. In a signal that combines a video format with reduced blanking and HBRA, the HBRA signal is truncated
and can present as either no audio or as problematic audio (static, clicking, absent, etc.). While Enova DGX
hardware supports both HBRA and reduced blanking video formats, these formats do not necessarily work with
one another.
To resolve the issue, change either the audio format to non-HBRA or change the video format to a format that
does not use reduced blanking.
Dante Audio Switching Board defaults to "Embedded" rather than "Switched" audio:
Audio Switching Boards default to Switched audio but, if the system was upgraded from Enova DGX 8/16/32/64 to
100 Series and then power cycled prior to insertion of ASB boards, the system may not recognize the correct
default state.
To resolve this issue, open the System Configuration interface and toggle the Audio Routing to its correct setting
(see page 138).
If you lose audio at destinations and in Dante Virtual Soundcard / Dante Via:
Check that all Dante hardware is powered and functioning normally.
Stop and re-start software.
IMPORTANT:
If all Dante hardware capable of providing a Master Clock on the Dante network is removed from the
network (even a short interruption), software dependent on the Master Clock for syncing will remain out-of-sync until all of
the software's processes are stopped and re-started (where the software sends a fresh request to the Master Clock).
