Sorry, a a couple of days away (vacation :-)).
OK I have installed the SONOS system and I run the music from the LMCE (as a NAS with samba) and it works well. Of course I can not control it from LMCE but I had to offer that to please my wife..... Her patience to the linux-system is rather non-existing for the time beeing. When I get time I will try out the web controller. It would be great to control this through an orbiter.
