Assuming that your real Squeeze devices have never been allowed to connect to the LAN side of your NC before then you should ....
Squeezeslaves are virtual Squeezeboxes that can be created on your NC (or MM's) and they make use of 2 of your physical audio outputs each.
Thanks Andrew, Squeeze hardware devices added - I suspect I will continue to control them through dedicated Squeeze hardware controllers, and Squeeze Apps for Android/iOS, but any issues adding them into same rooms/zones as MM's?
Virtual Squeeze added to core and tested working fine.
Tried adding one to a MM, and it does not appear to work.
Added the 1964 template to MM, then added #58 template under the Slim Streamer on the Core - matching fake MAC address on both. Did a reload, and ran Start_SqueezeBox_Slaces.sh
In the Logitech Media Server web interface ( http://core.address:9000
), I see all my Squeeze Hardware devices, plus the virtual squeeze device on Core, but no device for the MM.
Room assignments/zone is the same as the MM settings.
Anything I can check?
