switcher should be properly wired from the output of your source. Audio
signals connected to the output of your switcher should be properly
wired to the input of your destination device.
Confirm that any other amplifiers in the signal path have the proper
source and/or destination selected. Pay special attention to input
amplifiers that may be built into your destination device.
Replace the audio crosspoint module with one that is known to be
functional.

Take special care in noting the wiring configuration of balanced to
