I'm having a problem with the WebMessenger (v5). The notification sounds (the "ding" you are supposed to hear when you send or recieve a message) are not working when surfing remotely (not on the server)

    - surfing on localhost server : all sounds work perfectly

    - surfing not on the server : only the BUZZ sound works 
 

The sound alerts are an important feature.

Do you have any solution ?
