Hi,
All Audio goes through the audio Mixer.
The 48 Stereo or Mono Faders have Access to any of the channels on the SDI streams. So you can do Stereo pair selection (1-2, 3-4, 5-6, ... 15/16) or you can do individual channels 1/2/3/4/../15/16.
On Outputs embedding you have to select the channels for embedding from the Audio Mixer Outputs. (Main, Monitor, Aux 1- Aux12) you can not do "audio direct".
That would require something like an Ultrix with Full TDM audio Matrix.
