I have problems to get the ADAU1761 DSP to work on the evaluation board (mentioned in title).


I have followed all the instructions in on page 3 and 4, with no luck, I get no sound on the output. I connect each of the inputs in the Schematics to a Single Level Detector, they detect no input signal.

I have tried a white noise generator in SigmaStudio, still no output. I've even connected the white noise generator directly to the SLDetector, no signal.


In Hardware Configuration and Playback Output Signal Path tab I route both the LAUX and RAUX and get the input sound routed to the output. So, that's ok.


It seems as though the DSP doesn't start properly....What can be wrong?
