yep I'm a dumbass I for some reason I assumed the optical on the R1 was an input all this time
**note to self** get glasses
I was thinking along the lines of UA5 adc > optical > R1 optical 24bit. Obviously I missed the boat on this one.
Maybe I should just sell my 4runner and Vanagon that is wasting space and just get an R4 Pro and be done with it.
