Sound has always been working after installation of OpenSUSE 13.1 (KDE)
Suddenly all sound is gone. I suspect some utdate has messed up sound-settings.
I see that Master Volum was set to 0. In Yast -> Sound -> Other -> Volume, i can ajust volum to maximum and play testsound. This work, but all sound-stream is dead.
