I’ve recently upgraded to KDE 4.2.4 from KDE 4.1.3 (because I usually don’t upgrade until I notice something not working) and the sound is working randomly since then.
When I start an application using the xine engine, sometimes it works, but sometimes I get an error : the xine player simply not playing any sound, kaffeine saying “Loading of player part XinePart failed (All audio drivers failed to initialize!”. Then, I have to restart the sound drivers (/etc/init.d/alsasound restart), and launch the application again.
The sound crashes with a probability of only about 30%. Launching Amarok 2 (not Amarok 1.4) crashes it 100% of time, but that’s an exception.
When the sound is crashed, I can’t use xine nor yauap, but I still have sound in some other applications, e.g. videos/music played in a browser (youtube etc.)
I have no idea where i can find any logs or configuration files about this.
