Like so:

$(document).ready( function() {
    var pr_id = document.getElementById('id');

    $("#jquery_jplayer_1").jPlayer({
        ready: function() {
            $(this).jPlayer("setMedia", { 
                mp3:"/sounds/" + pr_id + ".mp3"
            });
        },
        swfPath: "js", 
        supplied: "mp3",
        wmode: "window"
    });
});

Concatenate the string with the variable :), unfortunately, unlike some other languages it's not as easy to include variables in string, and you have to split the string up a bit with the concatenation.
