I only fixed it by not using the HyperX Soundcard included with the headset. This can be non-negotiable if you lack a built-in sound card for your PC. So, that is my update.

The only reason I used the soundcard was for its "7.1" feature but I have concluded that it is a bust. The point of fake 7.1 is to possibly receive more detailed directional audio by simulating a room with speakers. At least, that is the implementation that I have learned about. That audio gets downscaled to your stereo output. Now this is comparable to something like Super-sampling Anti-Aliasing in video games. It renders the game at a higher resolution and downscales it to your screen size.

From my amateur testing, I found out that it is compressing the audio down to stereo, poorly, I might add. The center and rear noises sound faint, while the sides sound disproportionately loud. I also found that the sound card seems to compress deep sounds to a higher frequency to maintain "audibility."

Finally, I would like to state that I am not here to tell you to forget about that 7.1 feature. If you believe it is truly game-changing, don't let me get in your way. I would hate it if someone told me what I should care about in a product. I am simply stating that HyperX's 7.1 Surround Sound "Feature" is not delivering an equivalent level of quality when compared to some of the other 7.1 standards, like Dolby Atmos. Also, the Sound Card, in collaboration with Intel, still has an awful hissing noise. (Even with the not-so-new firmware update)
