Mirillis Action! doesn't record game sound!

[ProdiG]

Okay so this has been bugging me for a long time now! Every time I record my voice in Mirillis Action! it records withour a problem, but when I turn Minecraft on it suddenly won't record neither the game sound or my voice! I have adjusted the Sound setting so they match the ones in the Action! but it just won't record sound. I tried everything! I've tried switching the mode on games and applications only but it still won't record the sound or my voice. I don't know what to do! The quality is amazing and I really don't want to switch to another recorder! My PC is a little weak, but I don't see that that should be the reason for this problem! So if anyone can help me, please do..
