For playback add the codec-side delay to the timestamp, for capture subtract it. This brings the timestamps in line with the time that was recently added to the delay reporting.

Changes since v1: Calculate nsec from frames, subtract delay for playback as well as capture.
return (nsec > codec_nsecs) ? nsec - codec_nsecs : 0;Is this correct? I would think for capture you need to add the delay, and subtract it for playback?
Should the capture timestamp represents the wall time when the sample is converted by the A-to-D? If so, would be the correct time be the codec delay nsec before what is reported here?
