Audio file is WAY shorter than video file

Hi everyone!
I've been using Audacity for a little while now and I've run into a few problems but I was able to fix them with a few tweaks, but this one is just...crazy really?
I'm recording audio and video at the same time (Gameplay), my video length is 18 minutes and my audio is only 6 minutes?! This is even before I export it from Audacity. Beginning and ending are just as they should be, but in between Audacity just cut the file and removed about 2/3 of me just talking over gameplay? Exporting it still gives me a 6 minute file (which is obvious, but I tested this to make sure it wasn't a visual part of Audacity that was bugged.
Example of my recording now: "So at one point I'm talking about so..and here I am talking about something else" It's just messed up, do you know any way this can happen and how I can make it go back to normal? Or make sure this never happens again?

Thanks,
TGz_Proud

This is not clear to me (as I don't do this kind of thing). Are you using Audacity to record the audio and something else to record the video?

If you split the sound from the video, you may need additional software for Audacity to recognize the sound format. It's very common for Audacity to play a "mystery file" at many times faster than it's supposed to be.

Install FFMpeg software.
