Does Sync3 do 5.1 audio?

[ImLivingOnTheEdge]

I tried searching for previous topics, and I found "Is Edge Sony Premium TRUE SACD 5.1 Surround?" with no replies. So, I fear maybe I won't get a response either.  But here goes.

 

Can the Ford Sync3 handle 5.1 audio? Note that I currently have a fairly high end audio system in my 2019 ST.  I have a gizmo, forget the brand, but it grabs digital audio from the car's bus and sends it via fiber optic to my DSP.  Thus, I actually have digital audio from the source to the DSP.

 

I currently only have it as 2.1, no rear speakers.  Just front 3-way setup (active) and a sub.  I was starting to consider putting in a 5.1 system.  But, I don't know if the Sync 3 will send 5.1 on its bus that my gizmo works with.  Come to think of it, that vendor will probably be the best place to find out.  I guess I will try that.  I just thought of that while typing this question.
