Hello I retried the crash route with the other setting and systemsettings crashed identically to the bug. So, Any test of the sound devices in systemsettings in Live mode causes a crash Hope this helps
systemsettings 4 is no longer supported, we do only support version 5 I can not reproduce this crash with the following combinations systemsettings 5.4.1 + Qt 5.5.0 systemsettings 5.3.2 + Qt 5.4.1 Can you still reproduce this hang on version 5? If you can still reproduce the crash could you please install valgrind and then run valgrind systemsettings5 in a terminal, try to reproduce the crash and add here the valgrind output?
