USB digital audio INPUT?

[mountainjim]

I'm trying to get digital audio input into my video recorder on the S9 plus.

I have a new Samson Go Mic Mobile lavalier wireless system.

So far, I can only get the analog connection to work (headphone jack input).

And that works only with the native video camera, not with my Filmic Pro software.

Anybody figured out how to get digital audio input working for the S9 plus?
(ideally with the Filmic Pro software app)

Thanks!

Digital audio is a PCM stream, using an optical connection - cellphones don't do that.
