Audio cuts, breaks and skips

[Funseca]

Mirilis Action is a great program and I love it but there is one problem that I've been having for a lot of time.The problem is that when I record gameplay of any game it will randomly skip or cup parts of the voice on the recorded file and it is very frustrating. I record with separated tracks in AVI and 720p and it's only the voice track that does this, the game track is fine.
I'm sure that it's not the microfone, because I've tried with 4 and it's always doing the same thing. Can anyone help me fixing this?
Thanks in advance.

Could you post a video sample where this issue occurs?

[Funseca]

Sure, here's a video from my youtube channel: https://www.youtube.com/watch?v=6VhQ9n0wyoU
You can hear the problem at 2 minutes, there are more parts that's just one of them. I don't think you need to understand my language to find the problem.
Thanks in advance

Does this issue occurs only when your voice is raised?

[Funseca]

No,I don't think so

Do you have any idea what's causing the problem?
