C25 and C23. They have been retrofitted to the boards by VLSI Solution.
Boards older than 1.15 lack some microphone components and audio quality may
be non-perfect on these boards (different kinds of noise can be heard). To get good
audio quality, remove R12 and R13 and connect R12A, R12B, R13A, R13B, C25
and C23 as shown in these schematics.
New VS1002/VS1003 boards all have microphone and other required components
fitted.
