/**
 * <p>QuirkSummary
 *     Bug Id: b/202799148
 *     Description: Quirk indicates that the audio encoder outputs incorrect timestamps after
 *                  pause and resume recording. On the problem device, the audio codec only refers
 *                  to the first timestamp of the input audio data, and then accumulates
 *                  timestamps based on the subsequent input audio data, but does not refer to the
 *                  timestamp. So if we stop sending audio data to the codec or pause the codec
 *                  when paused, then codec will miss the timestamp increment during pause
 *                  duration, resulting in a/v out of sync after resume.
 *     Device(s): Sony-G3125
