Interesting. The fact that you can see the update means that there's no problem with internet access, but for some reason downloading the new version fails. One guess is that perhaps a security software prevents access to the new version, but you're saying that you can download it manually and it works.

I can build a debug version of the tweaker for you, which will print verbose information, hopefully providing some clues about what's the problem.

Support for the recent updates of Windows 10 1909 was added in 5.11.0.1, and will be incorporated in the next non-beta version of the tweaker.

This option is provided out of the box by Windows. Right click on the taskbar and choose to hide the button.

I’ve just released v5.11 which adds compatibility to the Windows 10 May 2021 Update.

I'm not familiar with such a problem. Does it work when you click on the volume tray icon?

If you find a way to reproduce the problem, let me know. For now, you might want to consider using the classic volume control. Refer to the advanced options in the help file for more details.

I support your choice to put it in Ideas rather than Bugs.

Before I add any of your feature requests, which are quite specific to your unique problem, how about the following solution:

1. Find a command to fix your volume balance, e.g. by using the SoundVolumeView tool.
2. Create a shortcut for it, or even better, set up a mouse shortcut for it using the tweaker.
3. Use the shortcut or mouse combination every time the balance is reset.

From the screenshot, I can see that you're using v5.10. Please update to the latest version.
