UR28M help needed: Mix 2 & 3 no DAW signal

UR28M configuration help needed

Is it normal the DAW is only played in MIX 1?
My MIX 2 and MIX 3 tabs don’t show or play signal from the DAW (or other media sources).

What could be wrong?

try assigning the output to mix2 or mix3 in your daw track output routing (activate it in your io routing first)
