I have a technical question about recording this game on pc using instant replay.

I usually play the game without my headphones on but whenever I change to online and meet someone there, I plug my headphones in to be able to communicate using my mic. So when I save the instant replay, there is no sound in the video after plugging the headphones. I did some experiments, tried 3 other games and this is the only game that happens. If I start the game with or without the headphones, it's fine. But if I change however I started, no audio afterwards. And I have to restart the game. Does anyone have the same kind of problem or do you know any solution or have any idea what would cause this at all?
