Just want to report back: Problem is solved! :D About two weeks ago I updated to kernel 3.17.4 (openSUSE 13.1 64bit). I am also using recent versions of ALSA 1.0.28 (from the openSUSE repo "multimedia:/libs") and pulseaudio 5.0 (from the openSUSE repo "home:/jejb1:/Tumbleweed") . Since then the issues are gone: After disconnecting the Axe-Fx II it disappears from KMix just as expected. Also the sound device for a running playback stream is directed to another sound card. On reconnecting the Axe-Fx II it reappears in KMix and a running playback stream is redirected to the Axe-Fx II, too. I don't know what change has brought the solution but am very happy. Many thanks to all - especially Daniel, Takashi and Clemens - who put a lot of effort into improving Linux and its sound system.
