My ACENet device channels have valid digital/analog I/O, but there is no audio I/O. What is wrong?

This symptom is seen when a Target using a software version prior to 4.17 is trying to use ACENet devices with firmware version 2.x. There are two solutions: either upgrade to ACE software version to 4.17 or greater, or downgrade the ACENet firmware to 1.x. ASTi strongly recommends upgrading to ACE software version 4.17 or greater.
