Can't use the distance of range, anymore. Since version 1.70.

class CfgSounds{

sounds[] = {};

class test
{
    sound[] = {"sounds\test.ogg", 10, 1, 500};
    titles[] = {};
};

};

Before the Update the Sound Distance (500 up there) was usable, in the recent version it doesn't work anymore.

Im not sure if this was on purpose.
