Distance between two entities decide volume of a sound.

I need help with an algorithm for my 2D Game. Say entity AA is emitting a sound. The strength of the emitting sound is determined by the distance between AA and BB(this could be the main character). The further away they are, the weaker the sound is. The max distance(pass this distance and the sound volume is 0) is of course customizable. The volume setting can be from 0.0 to 1.0. Where and when to do these checks is not a problem. I know my engine and I can resolve that. How to check it is the problem.

I noticed that I cant use any of the code in this thread because once the sound is playing, you cant change the volume(you have to stop it first).

What you need to do is change the volume/panning of the channel the sound is playing on, rather than just setting it when it initially plays. This will require you to implement a method of keeping track of which channel a sound is playing on.
