Hi forum!
I am using all i/o's (telejacks + Alesis ADAT linebox) back and forth to a mixing console. Works fine.

I want to use SPDIF as 2 extra stereo i/o to my console.
Output just seems to copy Main mix or what ever channels is set in UC:

SPDIF input doesnt work at all.

Is there a way to use SPDIF output as an individual 2 ch output, not copying another channel?
Should SPDIF input also work when using the ADAT i/o's?

Running a Mac mini M1, 44.1 kHz.
