Echo in my game while recording

[Shot fighter]

Hi it's me again sorry

I fixed my first problem but in my first couple of audios there is no echo in game, however a couple of audio tests later and there is an echo from the characters in game (Although I cant hear it, until I end the recording and watch the video my self.
Pls someone help me
I'm hoping its an easy fix and it isn't in my end.

Thanks

Can you turn off microphone recording in FBX and make a new recording. If you still get this echo, let us know. When we've seen this before its been because the game sound is picked up by the mic.
