This can be easily verified by clicking on the audio icon in the taskbar and changing the volume level: if it takes longer than 100ms for the audio notification previewing the volume level to sound, you are probably affected by this problem. Garbling of the first ~half second of audio output after a period of silence.

m_pAudioStream->time_base = (AVRational) {1, 9000}; // actually no need to set as 9000 is already default value for audio as you said m_pVideoStream->time_base = (AVRational) {1, 9000}; should be set as now both audio and video streams are …
Audio/video synchronization, TS MPEG2;H264/AVC ...
https://stackoverflow.com/questions/4728533/audio-video-synchronization-ts-mpeg2h264-avc-understanding-pts-in-handbrake
Appendix: My take on the handbrake A/V paper is this: At "expected" 100, the offset is calculated as video pts (100) - audio pts (0) - the internal PTS, to bring the audio up to the same presentation time, thus giving a pts offset of 99. at 105 the offset would be 105-5 = 100, not 99, but we proceed to use 99 as offset since there's no need to recalculate (100-99 = 1. 1/fps < 100ms).

3. Set an audio delay. Under the ‘Sync Offset (ms)’ column, enter a delay for the audio source in milliseconds. 1000ms = 1 sec. You might need to experiment with this option in order to correctly sync the audio with the video.
Saved Video has Delay in MediaInfo but In Sync. Re ...

The delay shown in MediaInfo is actually a differential between the time stamp of the first audio frame and the first video frame. Players use a clock to determine when to play a specific sample so that differential has no bearing on the sync because the player will only play a sample when the clock reaches it's designated time stamp.

#1742 (Wrong PTS values for aac) – FFmpeg
https://trac.ffmpeg.org/ticket/1742
Hole stream duration is ~5s, but audio PTS goes to ~334s. I think that this I is bug inside ffmpeg library. I also try with latest master version from git git://git.videolan.org/ffmpeg.git and I got same think. I successfully fix this by changing avidec.c. ffmpeg version 0.10.2 and 0.11.1.
Audio-to-video synchronization - Wikipedia
https://en.wikipedia.org/wiki/Audio-to-video_synchronization
Presentation time stamps (PTS) are embedded in MPEG transport streams to precisely signal when each audio and video segment is to be presented, to avoid AV-sync errors. However, these timestamps are often added after the video undergoes frame synchronization, format conversion and preprocessing, and thus the lip sync errors created by these operations will not be …
sonos beam audio delay samsung tv - pts-me.com
https://pts-me.com/nbkfu/sonos-beam-audio-delay-samsung-tv.html
Audio delay with Xbox One X and Samsung TE8072 using Sonos Beam. That delay, however, is sufficient to render most content unwatchable and the complainants’ frustration with this is apparent from some of the comments. I get audio delay when sound output on the xbox is set to Bitstream, if I switch to Stereo Uncompressed it is fine.
