I didnt find a solution,i reinstalled my system new.Net install with 14.04.4 starting fresh,made update and upgrade,installed LinuxMCE,did a update and upgrade once more e few days ago.Im now at 2.0.0.47.201602141633+a332f49a. And all is running fine for me now so far. And i can tell 14.04 is a real beauty atm.I got i lot running.
I think my bug was coming from doing update and upgrade under KDE in terminal on the core.Kubuntu bugs my soundcard,so maybe this was the fault.If i switch to KDE i dont have sound in Linuxmce when i switch back until i do a reboot of the core.Im doing now update and upgrade only over ssh and had no issues so far.
