Hi Carlos,
Yes, you can route Dolby-E through Ultrix. We recommend enabling "Audio Bypass" in the configuration for inputs with Dolby-E. When enabled, when a video source is routed to a destination, it will override the audio routing but ensures proper alignment of the Dolby metadata.
If "Audio Bypass" is not enabled, it is possible to shuffle the Dolby-E to a different audio pair, but there is no guarantee about placement of the metadata in this case. Also, you would not be able to breakaway the Dolby-E audio pair, as the VANC/metadata is carried with the video.
Frame sync should always be disabled on any input carrying Dolby-E.
Cheers,
Alun
