Given that our CI is passing without error, we need a lot more information here:

What MSVS version? How are you building PortAudio? Are you using the shipped, project files, CMake or some other build method?

[sevstels]

vs2010 The files were added to a common console C++ project in the usual standard way. But this unfortunately does not work. I temporarily got around the problem by using a dll, but it's not a solution. With the dll everything is assembled and works fine.

I'm not sure what "the usual standard way" is but PortAudio sources will not build without the correct build settings. You'd need to at least make sure that you are setting all of the include paths and defines correctly in the project build settings.

Can you try CMAKE gui?

[sevstels]

I can't use CMake. Because the whole huge project is built in Visual Studio.

[syntaro]

ah, CMake GUI will Create VisutlStudio Project file. Once you could try CMake, It will work. CMake -> Customize Build Option -> VisualStudio Project File. Make library and reference it from your main project.
