Hi Lisa,

When setting up the aggregate input the order in which the devices are selected under the "use" column determine which devices will appear to Pro Tools first.    The pictures look right but don't indicate what order they were selected in.

When setting up the aggregate input click/select "use" Dolby Audio Bridge before Avid HDX.    The table in this article may help.
