Are all of your speakers now working? Once you switched the ipv6 setting
off did you then need to do anything else with the speakers? Or did they
just magically work?!
I have the same issue as many of you guys above in the thread. The weird
thing is, I have 6 or 7 devices around the house and only two are
causing me the issue. So rebooting the wifi, resetting up etc is just a
waste of time, it is specific to these ...
