These are the processes that is needed to be taken:

6.  All the resync audio do not have keyboard shortcut, so we are going to create them. You can use any value but I advise using Ctrl + Shift  and then we give value of 1 to 7 for each resync option
7.  So to give the value, click on any of the resync audio and press the keyboard shortcut or hotkey you wish to give and after through click on Close

5) Shift + Ctrl + 5   Resync audio -5milliseconds
6) Shift + Ctrl + 6  Resync audio +5milliseconds
7) Shift + Ctrl + 7 Resync audio(Back to Normal)
The keyboard shortcut or hotkeys required for this process are
Shift + ctrl + 1 to 7, using the timing of 5 seconds, 50 milliseconds and 5milliseconds to sync the audio to the video.
Shift +ctrl + 1, 3 and 5 stands for audio delay up, should be used when audio is faster than video
Shift +ctrl + 2, 4 and 6 stands for audio delay down, should be used when audio is slower than video.
Shift + ctrl + 7 to return audio to normal state or original state (that is the way it was by default).

  1. Using current x64 Windows version. May 2020.
    Nothing seems the same as depicted here.
    Called “Options” instead of “properties”.
    Many changes to organization.
    Playback has its own section.
    But sync subsection area in playback is grayed out, and doesn’t appear to include changing the audio sync in ms.
    The only changes I can use is “+” & “-“, which shift audio by +/-10ms.
