I do not have a IC-9100.  Thought about it but ended up with a IC-910H
to go with my IC-746Pro.

On the 746, to send and receive audio from the ACC(1) connector on the
rear, you need to be in the "D" mode - i.e., push and hold the SSB (or
FM or AM) button until the D illuminates next to the mode indicator.
If you don't, the radio expects audio from the mic port.  I assume
