Yes, this is possible:

- the tda998x codec may call the tda998x hdmi in the hw_params()
  function, i.e. when the sample format is known, and then,

- the tda998x_audio_update() function may have the audio parameters
  (struct snd_pcm_hw_params) as an argument, and CTS_N_K may be set
  to either 1, 2 or 3 for SNDRV_PCM_FORMAT_S16_LE / S24_LE and S32_LE.

This is working in my machine. Would it also work for you?
