Bad audio quality (system sound)

[Japsis]

Hi!

First of all, before using Action! i was tried Fraps, but with Fraps sound quality when I recorded games, was pretty poor. Audio sounds little thick like too much bass or something like that.
My youtube video with Fraps (bad sound) - https://www.youtube.com/watch?v=00UuZYnTo58
Not my youtube video (good sound, same as ingame) - https://www.youtube.com/watch?v=pdeCzkSrQqo
I thought that maybe other recording program will fix this so I downloaded trial version of Action! but your program makes same sound quality like Fraps. No matter video recorder ingame or just desktop.
I have HP ENVY dv6-7300sa (i7-3630QM, 8GB RAM, GT 635M, IDT (Beats audio), Windows 10 Home x64). All drivers is up to date. I tried disable IDT Beats Audio program, I tried change Windows Sound Properties settings but nothing helps.

Hope for help, thanks!
