[Aggarwal, Anuj] There is nothing specific to my use case. I am just 
trying to playback an audio file (16bit, stereo, 44.1khz) and hearing 
this sine-tonish sound everytime in the beginning.
This artifact was not there when I was using ALSA; it started coming
only when I moved to the newer ASoC framework.
