On Monday 17 March 2008, Olivier Goffart wrote: > KNotify block beacause of a deadlock in xine or in the xine backend. The state I understand from the backtrace: The main thread is trying to create a new stream for playback, but blocks because the phonon-xine internal xine thread was already blocked waiting for a xine_open to finish. Why the latter blocks I can't see, there could be multiple reasons, one of them a bug in libxine, but possibly also a problem with your filesystem or the soundcard. If the deadlock is reproducable then please enable all debug output and add it to the report: export PHONON_DEBUG=1 export PHONON_XINE_VERBOSITY=99

This happens to other people as well (Bug 156236)
Have anyone experienced this bug again with a recent KDE version? (4.1.3 / 4.2beta2 / 4.2svn) ? Thanks :)
SVN commit 903113 by mkretz: when all devices fail don't hang forever on the last broken device but rather fall back to a null output so that everything behaves properly - just without sound. The new string for better user feedback can wait. BUG: 159469 M +15 -4 phonon/audiooutput.cpp M +6 -0 xine/audiooutput.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=903113
