One of the replies mentioned the same problem but I don't quite get the solution. I intended to generate 16 kHz tone with the DAC but beyond 14 kHz the audio codec just went mute. I tried changing the sample rate to 88 kHz but it made no difference. What seems to be the problem?

how are you generating the 16kHz tone? are you using the sine_generator example?

how are you testing for the tone? are you using an oscilloscope, or headphones plugged directly into the HP_OUT on the codecshield? or are you going through another amp?
