The HDSP Totalmix mixer does not switch its inputs to reflect the changes in the Adat lightpipe protocol at 88.1kHz and 96kHz. Because Adat Lightpipe works at a maximum of 48kHz, the SMUX protocol for combining two channels into one came about to achieve these higher sample rates. So Input 1 is combined into channels 1&2 in the DSP mixer, Input 2 is combined into channels 3&4, and so on. You'll need to switch the outputs in the middle column to go to outputs 1, 3, 5, etc.
