EVAL-ADAU1X61EBZ

Hello,

 

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

 

I have followed all the instructions in http://www.analog.com/static/imported-files/eval_boards/EVAL-ADAU1761Z.pdf 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?

 

Thanks,

Helge
