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

The following fixed it for me:

1. Click Start, type sound and hit enter to open the sound window. Alternatively, right-click on the sound icon in the tray area and select Sounds.
2. Select the Playback tab and then right-click on Speakers and select Properties.
3. Go to the Enhancements tab (if you have it) and uncheck Disable all sound effects (or any similar thing you might have in there).
4. Also, uncheck the immediate mode on top of the list.

For me, it immediately fixed the problem, so give it a go and see what happens.
