Unfortunately, Windows volume settings are not saved for applications running in the sandbox. At least, I haven't found a way to save them. Alas.
I use the global volume level for such games to lower the volume before launching them. Or I don't play such games at all — if the developer is too lazy to make such a setting, their game is most likely shitty.
so true. reminds me of countless games from the Flash heydays, always an annoying soundtrack at max blast, and no setting for it.
Sandboxie doesn't really come with it's own mixer, right, i suppose one could maybe create such with a VM; that's different.
i'd recommend a keyboard with volume wheel, works for me because it usually directly uses the system's global
main (aka speaker, output or summary on some systems) slider.
