       var audio="http://xxxxx/xxx/xx-xx-123.m4a"
       var myOtherOne = new CirclePlayer("#jquery_jplayer_2",
        {
            m4a: audio,
        }

Answer 1

If possible, I'd use ES6 syntax for this:

`"${data.url}"`

Answer 2

var audioUrl = "\""+ data.url+  "\""; 

Whatever your get audioUrl and you want to wrap it with ", you need to put them and escape inner ones with . Above will result in:

 "http://xxxxx/xxx/xx-xx-123.m4a"

OR if you are using the single quotes then no need to use the escape character.

var audioUrl = '"'+ data.url+  '"';
