Some vendors, e.g. Samsung, have done some hacks around there, providing more precise audio controls if you drag the audio slider by hand. I don't know if there are any programmatic system-wide ways to do the same (every app can implement it in their software mixer though). I haven't had great experience with third-party solutions that obviously cannot integrate with the OS at the same level.
