Hello awesome RME forums, I've heard such great things about this community, and now you've become my last resort for help.

I have the RME Digiface USB and it worked amazingly up until a week ago.

My issue:

Everything works perfectly except for when I have my Focusrite 18i20 connected through ADAT in/out - it will output sound through the outputs and headphone outs just fine, but I can't get sound through the preamp inputs of the device. If I choose Focusrite ASIO as my DAW sound driver, sound comes through just fine.

ALSO if I connect other sound devices (Octopre, ADA8200) the inputs from these devices go through just fine into the DAW.

I have a suspicion this has something to do with the 18i20 being also my WDM sound card, but even if I disable it in windows, nothing changes. I can't see input in the Totalmix software either.

Can anyone help?
