To set volume to fixed value (say 60%) at the track start use:
mplayer -volume 60 file1 file2 file3 ...

It's irrelevant whether you are using -af volume filter or not (though
exact result will be a bit different depending on it).

What, however, most people prefer is keeping volume at the start of next
track just as it was set at the end of previous track. This is done
automatically when you use pulseaudio and -ao pulse mplayer driver
(though probably not a solution for universal audio player).
