Hello John,
I took a look at your project, and wonder if you were transmitting to the right output channels. It looks like you are trying to write to serial port output 7 (channels 14 and 15).
However, under the Serial I/O register window, you have Serial Port 7 disabled (which by default I2S would use channels 14 and 15) and you have Serial Port 8 enabled as a 16-bit slave (Serial Port Out 8 would use channels 16 and 17 within SigmaStudio). Does this explain why you don't hear anything on J11?
Also, I notice you set the project to 32 kHz, but assuming the use of the ADAU144x eval board the clock input source by default is 12.288 MHz, with the serial ports configured as master to run at 48 kHz I2S. Setting the sample rate in the project is for generation proper coefficient values, but this does not contol the start pulse rate for the core and serial port master clock frequencies.
Finally, I am confused how you are seeing a 44.1 kHz signal. Is this an externally master I2S clock? Or do you have a external 11.2896 MHz master clock source clocking the DSP to generate that sample rate?
