SoundVolumeView is a tiny portable tool which displays the current volume levels for all the active audio components on your system, and allow you to mute or unmute them instantly.

It's also possible to save your current volume settings as a "profile". Reloading this later will instantly restore the same volume settings.

The interface for all this is extremely basic. There's no audio meter, no slider, no colourful graphics - it's just the usual NirSoft table, crammed with data.

But, if you're happy to use the program's command line interface, there are some usual features here.

Create a shortcut to run it like this, for example:

SoundVolumeView.exe /SaveProfile test.vol

...And it'll instantly save all your current volume settings in a file called test.vol.

Now create a second shortcut with this:

SoundVolumeView.exe /LoadProfile test.vol

...And it'll restore all your previous volume settings on demand.

Version 1.55:

Added 'Decrease Volume Step (dB)' (Ctrl+7) and 'Increase Volume Step (dB)' (Ctrl+8) options which increase/decrease the volume accoding to the default volume step displayed in 'Volume Step' column.
Added 'Export All Items' option.

Verdict

The interface is dated and technical, but SoundVolumeView is handy as a way to tweak or restore your volume settings from scripts or shortcuts.
