@tomangelo have you figured out #823? Shouldn't there be some kind of "pause" function for audio stream? I didn't take a look at a code, just guessing.
Where do you get those DLLs from? Are you using a package for MSVC from the forum? It should contain a "bin" folder where all necessary DLLs (even more) should be.
"libpng16-16.dll" doesn't match "libpng16.dll". Just rename it. I'm happy that the fix works though. I'll add a flag for gcc compilers to avoid such situations in the future.
