After a fair amount of horsing around, I succeeded in getting Skype 2.1.0.47 to work on pulseaudio on 11.1/KDE. The most persistent problem was getting the webcam mike to work, which I solved by running pavucontrol and selecting the webcam mike there.
Am having persistent problems getting the webcam mike to work on 11.2 (testing with krecorder), which lacks pulseaudio. I attempted to install pulseaudio on 11.2 from YaST, but YaST wanted to uninstall a ton of 11.2 KDE stuff to resolve conflicts. I was afraid to continue for fear of getting an irretrievably scrambled system.
Any suggestions?
