-----------------------------------------

             Summary: WP7 : Cannot play MP3 using MEDIA
                 Key: CB-941
                 URL: https://issues.apache.org/jira/browse/CB-941
             Project: Apache Cordova
          Issue Type: Bug
          Components: WP7
    Affects Versions: 1.8.0
         Environment: Nokia Lumia 800 with WP 7.5 (7.10.7740.16). 1.8.0rc1
            Reporter: Christophe A. Guilmart
            Assignee: Jesse MacFadyen


The MP3 file is only played once (the first time).

* If I create a new instance of MEDIA each time, the MP3 file is only playe=
d once (the first time).

* If I keep alive the instance (create it in onDeviceReady), I can play mul=
tiple time the first mp3 I play. BUT, I cannot play the other mp3.

note:=20
* with version 1.6.1, turn OFF then ON the screen allow you to play one mor=
e time the mp3. Not with 1.8.0.
* same issue with 1.6.1, but the error message are IOException & IsolatedSt=
orageException with various "MEDIA on status" information.=20

      var my_media =3D null;

        if (!(my_media =3D=3D null)){

        }
