The crash is also reproducible with Dragon Player, Kaffeine, and MPlayer with audio only, but not with MPD (Music Player Daemon). Reassigning to the Pulseaudio Backend Component since PA seems to be involved in the crash. Created attachment 66608 [details] Crude attempt at finding the cause Using this crude (bad formatting etc.) patch I see that "kmix(9489) Mixer_PULSE::removeWidget: MixDevice deleted" is printed and a while later "kmix(9489) MDWSlider::update: Tying to update even though mixdevice was destroyed" every time just before the crash happens, so it probably has something to do with MixDevices being automatically destroyed. Also that MixDeviceWidgets aren't correctly removed from ViewDockAreaPopup. See bug 288637 that they don't seem to be added, either. Created attachment 66609 [details]
New try (the first one wasn't correct)
I can't reproduce this anymore after bug 288637 was fixed. Stefan, can you confirm it is fixed? Yes. A test would be very appreciated. It might also be related to 288675. Please try again with the newest from branch 4.8 (or trunk). I might have just fixed that today. *** Bug 295530 has been marked as a duplicate of this bug. *** Bug 295530 is from KDE 4.8.1, so it's not yet fixed. Created attachment 69635 [details]

This is a good time to test if you can easily reproduce the crash (I am not able to do so at all, as it never crashes for me, independent on the chosen Backend). The complete change to MixDevice is commited to trunk. There is more to do (especially for hotplug/unplug of complete cards), but this change is the most important one. If at all, I am expecting memory leaks but hopefully this should bring a lot of stability. PS: This bug report (and the duplicates) are similar to bug 290742. This here deals with the DockArea and the latter with the main window. Both are about referencing a "dead"/destroyed MixDevice. Merging all bug reports that have a backtrace that indicates access to a dead/destroyed MixDevice to Bug 290742 *** This bug has been marked as a duplicate of bug 290742 *** (In reply to comment #65) > Testers needed for Trunk version of KMix.

I can help test too. on my system (SuSe 12.1 KDE 4.8.1) Kmix crashes on every system boot - easily reproducable.
