I have added a Play 1 to my Sonos Connect (Z80 I think). The Play 1 is fine but now the Connect only plays a couple of seconds, stops and then repeats after 5 - 10 seconds. This only happens when the Play 1 is in use. As soon as it stops the Connect works fine - as it has done for a number of years. I have put all devices on static IP addresses. Restarted everything, router etc, but to no avail. Help! I have submitted a diagnostic 6956467.
