Not able to configure my playback device to MONO . But my playback device supports MONO. What is wrong in the below configuration
Error : Channels not available for PLAYBACK device

retVal = snd_pcm_hw_params_set_channels( pcm, hwparams, 1);
  if (retVal < 0){
    printf("Channels not available : %s\n", name);
    return retVal;
  }
