The output audio has been run faster when converting audio sample rate from 16Khz to 44.1 Khz using Micrsoft Media Foudation

I created a SinkWriter that is able to encode video and audio using Microsoft's Media Foundation Platform.
Video is working fine so far but I have some troubles with audio only.
I converted audio sample rate from 16Khz to 44.1 Khz, the ouput audio ran faster than the input audio.
The only bug that appears in the audio codec is AAC with input audio  sample rate under 32kHZ.

What problem in Writesample function?
Given below is the sample test application:

#include <windows.h>
#include <windowsx.h>

#include <comdef.h>
#include <stdio.h>
#include <mfapi.h>

#include <mfreadwrite.h>
#include <Mferror.h>
