qwvolumecontrol | volume control for Windows

qwvolumecontrol is a C++ library. qwvolumecontrol has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This is a volume mixer for Windows. It exists because sndvol.exe has the rather annoying property of scaling the appearance of session volumes so that 1.0 maps to the current endpoint volume, despite the API to all other appearances not in fact working this way. The UI takes a few cues from pavucontrol, though it can't take all the cues, as Windows' sound system doesn't work quite the same way. To build, you need Qt 5.7ish, the Windows SDK, and MSVC 2015. It uses the smart pointer library that MSVC supplies as comsupw.lib, so I doubt MinGW will work. Beware: You will not get meaningful channel names until you've gone through the wizard in the Windows audio settings (the one under "Configure"). Until this is done, that information is extremely hard to extract.
