Windows Audio Auto-adjusting

[Mendokusaii]

Hi!

(TS3 plugin and Windows communication settings are fine - http://imgur.com/a/5HVzh - these are all that I know of)

Today I cleaned my PC, plugged everything out of my PC and then back in.
I plugged in a new extra monitor using HDMI.
After this, my sound has been acting weird.
It started off as initially a lot louder than before, everything is.
System sounds, music, games, etc. I'm listening to music using Chrome, it starts off rather low but increases slowly.

The volume panel does not change (it remains at full - http://prntscr.com/8pzrej).
Meanwhile I'm in teamspeak with my friends muted.
If I unmute the unmute sound is really loud, and after my friends have made enough noise the mute sound and the music is low again.
Roughly the same as before the issue.

I have tried:
-Updating Realtek drivers
-disabling drivers related to HDMI /two nVidia drivers
-Tried both back and front panels for sound with no difference
-Trying various Realtek settings
-Plugging out HDMI monitor
I'm using
Windows 7
Professional 64bit.
ASUS GTX 970 4GB
I7 5820K OC
G.SKILL RIPJAWS 4X4GB DDR4
MSI X99S GAMING 7

Thanks in advance!

This was weird, it didn't work the first time. I tried restarting it, but the settings were ticked in even though I just turned it off.
I tried it one more time after that and now it works, atleast so far. I don't know why it re-enabled itself but it's not doing it anymore it seems.

Thanks for the insanely fast response.

No problem
I'm glad you have resolved your issue.

Feel free to come back if it keeps on happening (The re-enable issue)
