Log Message:
H
Fail AUDIO_DSP_HEARTBEAT
In the initial release of the software this message can be a false failure if the processor
gets too busy. For example, if restoring presets with very different settings. If the audio
function works OK, but this message still appears occasionally, then upgrade the
software to the current version, clear the log, and bench test to see if the problem
persists. If it does, then search for an intermittent problem in the audio board, cables, or
main board.
