Hello,

I've searched through various posts and did not find an exact answer to my question yet.

I am using a Babyface Pro FS connected to a Windows 10 computer. The Babyface is connected via ADAT 1 ports to my old Fireface 800. (Babyface <-- Adat Out Adat In--> Fireface 800
Babyface <-- Adat In Adat Out--> Fireface 800)
From what I have found on the forums I believe I have this configured correctly. When I open fireface usb settings for the babyface it is running the main internal clock and detects ADAT and lists "Sync @ 48kHz" (I've also tried 44.1kHz). As for the configuration of my old Fireface 800, I used my mac laptop to set it into stand-alone mode via fireface settings and it is also synced to the Babyface Pro FS.

I am trying to use some analog equipment via balanced line inputs on the rear of my fireface 800(as I had configured previously, inputs 1-3) They still work when connected to my mac and signal is definitely coming through the analog equipment and RME fireface 800, but nothing in Totalmix FX aside from AN1.

My issue is trying to route this signal to ADAT 1-8 channels in my Babyface Pro FS or even to Fireface 800 ADAT 1. I believe there is some major misunderstanding I have about the capabilities of ADAT or the routing in Totalmix FX. I have seen some videos where people use a similar expansion and it seems to work fine for them.

Things I have tried: My optical out is set to ADAT. I've tried ticking TMS on and off, changing WDM devices. I've tried every single input including the front pre-amps on the Fireface 800 to no avail, even using a simple line cable DI with guitar. I've tried reversing the ADAT Ins and Outs. I've tried both on Mac and PC.

If anything is too vague in my description please let me know. If you can offer any guidance regarding this issue I would be very grateful thank you.
