How to restore audio file

I recorded the screen for approximate 5 and half hours. I exported the same and the output has only video and no audio. However there was audio file in temp before exporting but now audio file is missing. Please help as to audio is very important

Hi,

If you don’t see the audio bar in the Timeline pane after recording like this image, it means that the audio isn’t recorded, unfortunately.
