How to change audio volume of a particular application in Linux

I wanted to adjust volume of a particular application(Not the entire system volume) in Linux using my c code.

Please suggest how can we do this in Linux.

Solution

  • First, you need to know what audio system your desktop is using.

    If it's PulseAudio (a popular choice, these days), then some API documentation can be found here:

    http://freedesktop.org/software/pulseaudio/doxygen/

    I'm not totally sure if that's the right API for your needs (controlling other applications) but it's a starting point, and I'm sure further surfing/googling will get you there.
