ADAU1701 stops working after adding filter

Dear all,

 

I`m trying to build a FM stereo coder wich works fine until I add a first order filter (preemphasis). Then the DSP just stops working.

After adding the preemphasis filter there is no output anymore. 19kHz and audio is gone. When I remove the preemphasis both audio and 19kHz is back. The program is running at 192kHz. I have correctly set the core to 192kHz 4x256 instructions.

 

Wat could cause this problem?
