Windows 10: Constant Audio Fluctuations?

Hello everybody,

Here is a 20 second clip that shows my issue better than I could explain it; Audio Problem. - YouTube

It happens with no windows open or multiple windows open, when recording and not recording, and every day. I've reinstalled those drivers and updated every other driver that wasn't up to date.

I do lots of recording so having unreliable audio is a massive problem, and I've been having this issue for about a week solid now. I've spent hours reading forums and following all kinds of guides for fixing things that I thought could be related, but I just can't find a way to fix it.

I've attached my DxDiag, and screenshots of the Playback and Recording pages in the audio manager. I'd like to point out that my Razer Seiren microphone is registered as speakers under Playback too. Not sure if that's relevant but I've done everything I can find to stop that too.

Any help would be amazing! I just don't know what to do.

I have no idea what Virtual Audio Cable or Stereo Mix are. Everything that is operating is basically done because it was recommended or just equipped by default by whatever software I've installed over time.

I looked a Stereo Mix tutorial up and I still don't really understand how it is applicable to my situation. I don't hear (or want to hear) my voice back through my headset when I'm speaking/recording.

I completely uninstalled Virtual Audio Cable and the problem persists, even after setting Stereo Mix to default.

The problem also persists even with my Microphone unplugged.

Here's an image of my results after running LatencyMon for over six hours. audioscan — Postimage.org
I don't experience drop outs, clicks, or pops, just the issue detailed in the first post.

I can't find any CPU throttling settings in the Control Panel, and I don't know how to update a BIOS.

Any further thoughts/advice? I really appreciate it.
