KMPlayer mp4 sound problem

First timer here, in need of a bit of advice ^^
I'm using KMPlayer as my media player, but I've run into a small problem regarding sound.

Currently watching Naruto; Shippuuden, however, a lot of the downloaded episodes are in the mp4 format. That in itself is no problem, but in KMPlayer I often hear a (Not sure how to put it) scratchy/raspy noise.

I've checked several of the episodes, whereas all have this problem, and I've also tested several players (Windows Media Player and VLC). Those players only experience general bad sound quality (As with KMPlayer), only without the annoying raspy sounds.

Currently using VLC for those files, but I'd prefer to go back to my main player, if anyone here got any advice on how to fix it.

I tried installing K-Lite Codec Pack, but there haven't been any difference regarding the problem. If there's another good codec pack that might do the trick (Haven't dived too much into that field) I'd be happy for any information. I've tried searching a fair bit, but alas, I haven't found anything helpful.

Thanks for any help :)

Hello, just wondering if anyone could teach me how to 2's compliment, with some examples. The wiki page is just not doing it for me. Thanks.
