Hi Andy,
it’s possible. I can change the plugin for you and to add a mute button.
If you want, you can create a new user to me in your admin panel. It is faster if I can change the code for testing. I have done this with other users and there were no problems. You can trust me. I only want fix this problem.
You can send me the information to my email address admin@creabox.es
