I was visiting my parents over christmas and they gave me a Sonos speaker which was part of their system before. Now i have difficulty setting it up because my phone (Iphone 5 with ios 8) does not have the option to create a new system. I cn just connect to an existing system. When i use the old system, which i can still connect to over the new wifi, I still get a connection but i cant play any songs. It always tells me there was an error but nothing more. How do i set this up and has anyone faced similar problems?
