Receive audio is on a different connector than the front panel mic
audio.  However, if the DSP board (or front panel) was not installed
correctly (misaligned/bent/broken pins on one or more connectors) it
could impact Line Out audio.

Connect a set of powered speakers to the Line Out jack and see if
you have audio there.
