Why is my recording audio is like this?

[alfdnl080]

I dont know why, but my desktop audio sounds very bad. You can hear like the surrounding sound in the game is louder than the game? i dont even know how to explain it.

I've tried looking all over the internet for a solution but I couldn't find anything. I would appreciate some help. Thanks in advance!
