Action! and sound in games

[UnknowN]

Hello, I have a problem with the sound in all of the games I played like BF3, F1 2011, COD:MW... and the sound doesnt work, but if while im recording in some game I play a song in AIMP3 the result is a video of the game with the music of the reproductor
Any solution to fix the sound in-game?

Hi, do you use standard sound card on motherboard?

Can you please check if audio only recording does work fine for games audio?
Please check this for "record silence" enabled and disabled.
