I don’t get why LMS sees Max2play names like SqueezeLite 1 and SqueezeLite 2 and so on. I check there name and they are not name that. How can I fix this?
Is the Multisqueeze plugin running on your Pi? The names may be assigned there. Otherwise restart the Squeezebox Server and your players. Maybe that already fixes the problem.
Please check the command line options of your Squeezelite players. A parameter may be set there that overwrites or blocks the correct name. Have you already checked whether Squeezelite 1 (etc.) is really the correct Max2Play player and is able to play music? In this case the names have been changed by the Squeezebox server. Maybe because of a plugin? The best thing to do is to try to start the server and only one Max2Play device and see what happens.
