EOF, '\\', "",'',db 0,'\\.',NULL,<0,0,0,0,0,0,0,0,0,0,0,0,0>

I find example this forum but can't change sound of line-in, only main and wave\mp3

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.
