Hitfilm audio is not working?

I've recorded Minecraft with someone else and you can hear in the recording as well, but I want to cut the video now, but you can't hear my recording partner in hitfilm, why ever, when I open the video through the library, I can hear him as I said. What could that be?

Do you have in Hitfilm both your microphone audio track and the desktop sound audio?

If not then it is clear that your desktop sound is not present.

I do not know where to set it, but usually you hear the desktop sound
