STA311B - I2S out not working

I am testing a new STA311 design and I cannot get I2S output from the IC. I have I2S input running at 48kHz with BCK, LRCK and System clock (12.288MHz) present (coming from an ADC). I2S output is enabled but I don't have BCK or LRCK coming out.

PWM output works in binary mode but I have no signal output in FFX mode. 

For the test, I use the APWorkbench to generate the register values and I program them via my own uC. I2C bus communication runs without errors, PWDN and RESET pins are high.

Do you have any ideas what else I can try?
