Most probably there's some WinAPI function for this purpose. Found this after quickly googling the issue:

Hi
You can do it with mixerSetControlDetails API in MFC I suggest you go to this link :
mixerSetControlDetails[^]

However you can use it from C# and you don`t need use MFC unless you have. for example you can call this API from c# with DllImport:

C#

[DllImport("winmm.dll")]
private static extern int mixerSetControlDetails(int hmxobj, ref MIXERCONTROLDETAILS pmxcd,
    int fdwDetails);

Best Regards.
