Hello all! I figured out the problem myself... FINALLY! So I was having this problem for a long time and fixed it by accident. So if you have Windows 10, here's the problem & fix..
We MUST enable Windows Sonic for Headphones so that it tricks your computer into using those codex to process the sound. (Windows Sonic Spatial Sound is free to use) I turned my audio all the way up to Studio Quality 192000 hz and it sounds crystal clear and perfect, but it helped all the different frequency options so go with what works on your PC.
What you'd need to do is open up your audio properties, by right clicking on the audio icon on your Windows Task bar, it looks like a little speaker icon. From there, you'd choose "Spatial Sound with Windows Sonic" and hover over that, to be able to then click the option "Windows Sonic for Headphones". It'll still play the sound from whatever speakers you have setup on your PC.
What causes this: It seems for some reason those of us with higher end spec computers and audio (my Dell XPS 27 for instance has 4 speakers, a subwoofer and 2 radiators) have problems with the way audio is processed in the background, so by shifting that to Windows Sonic it corrected the issue. I haven't had any lag or other issues arise from this.
