AD1451's Noise Reduction project has no audio output.

Hi Sir,1

    I download the ADAU1542's Noise Reduction project and try to evaluate on my ADAU1451  board .  I only changed the Audio In and Audio Out of the original project . But there is audio output.

I attached the project, can you check it for me. The Sigmastuido I used is 4.3.3.
