Question:

Why do mixer outputs or individual channels have no audio even though there is meter movement?

Answer:

There are 22 Inserts available on Si mixers.  ​These create a “loop" to Send and Receive from another device and can be Inserted on any channel, and any Output.  If there is an active Insert assigned, and that loop is not complete (plugin broken, patch bad, device itself not passing audio), then the audio chain will be broken at that point of insert. To check, select the Insert in option on the screen.  If you see any Inserts assigned, try momentarily setting them to “Unassigned" and see if audio flow returns.  If this fixes the issue, then you must investigate the Insert or Plugin for issues before re-inserting.
