I'm trying to write a callback function for SDL_mixer through Derelict, but this is the first time I've tried to use a function as a parameter, and so I think I'm just making a minor mistake somewhere.

Make it a C function, not a D function:

extern (C) void channelDone(int channel)
{
        unmuteMusic();
}

and use & to reference the function instead of calling it:

Mix_ChannelFinished(&channelDone);
