Error Initializing ad193x HW Parms

I am using the BF537, and am trying to setup and communicate with the ad1939  4-IN,8-OUT CODEC.
The ad1939 is SPI-controlled, uses I2S (TDM mode), and uses SPORT 0.

PROBLEM:

  After successfully calling snd_pcm_open(), I am getting an error returned after calling snd_pcm_hw_params_any().

  Error:  'Invalid argument'

Please see attached file.

Thanks for your help,
