Warning: The audio API that uses MIXERLINE structures is not supported in Windows Vista and later.

I was really disappointed about that because I had written several programs that used that API. The API that replaced it is COM based and not documented very well, I gave up on trying to use it. There are some other options for controlling audio and examples of such are in this forum.
