I'm fairly certain that the issue was with CIC mapping then. If your
CICs were mapped correctly, and you're talking in both directions in the
call (which you should be in this test), you should see audio in both
directions, TX and RX. In cases where you have CIC mismatch, you will
see audio in only one direction (either TX or RX depending on whether
you are on the right or wrong channel).
