Hi Will,
The external audio plug-in is the way to go. That being said…
Can you give us a few details of your system such as:
Which operating system are you on?
Are you using another audio interface, if so which one?
Are you trying to use it as an aggregate device (if using Mac) with the H9000?
If not, is the H9000 set as your main audio interface in preferences?
What does your Direct Routing page in emote look like?
In the interim, this video may provide guidance depending on your setup.
