Windows 10 volume randomly jumps to 100%

Today I installed Windows 10, and I love it except for this bug:

The volume has a bug. When I'm watching YouTube videos on Microsoft Edge and I click next video, my ears will be blown off because, for some reason, the volume is all the way at 100%, until I tweak it with the function key on my keyboard. It then says it's at 30% and suddenly the audio jumps back down to 30%. This mostly happens with Edge, and since Edge does not have a spot in my volume mixer, there's something funky going on there.

Every time Edge loads a new video or audio element, the volume will jump to 100%, also sometimes when I switch between tabs, it will do the same.

I've also had Windows notification sounds jump to 100% in the volume mixer too. This is very frustrating as I am sometimes using a studio monitor, and having that blow because of a bug is just silly.

Are there any known issues with volume in Windows 10?

I should also mention that there is no headphone device in the volume settings, which there were before the upgrade.

It's a driver (Realtek supposedly) problem with Windows 10 that causes this issue: when playing a video (YouTube, local file, etc.) and you pause the audio, playing again would result in a volume change without any real change in the speaker volume meter.

The following fixed it for me:

1. Click Start > Type sound > Enter to open Sound settings
   (Alternatively, right-click on the tray area Sound icon and select Sounds)
2. Playback tab > Right-click Speakers > Properties
3. Enhancements tab (if existing) > Uncheck Disable all sound effects (or similar option)
4. Uncheck Immediate Mode at top of the list

EDIT: For users that have Advanced tab instead of Enhancements:

3. Go to Advanced tab
4. On Signal Enhancements section Uncheck Enable audio enhancements

I have fixed the Windows 10 audio issue on my laptop by doing this:

1. In the lower-right hand of the screen, click system tray.
2. Right-click the audio icon then click Sounds.
3. A new window appears. Click the Communications tab.
4. Click the radio button for Do nothing and click OK.

My machine was interpreting something as incoming or outgoing communication, thus initially lowering the volume.
