This is more or less your logfile from the GnomeDiaplayManager. It woud be helpful to get the backtrace of the segfault or grep the logs for (pulse|libasound). I assume there is a problem with the libasound_module_pcm_a52.so There is a similar bug in https://bugs.archlinux.org/task/60616. Upstream has a patch at http://git.alsa-project.org/?p=alsa-plugins.git;a=commit;h=a4e7e1282c57a2f4e83afe9a4008042d8b4c5bb9 which I can't test because here is no a52 device available...... Elimar -- Numeric stability is probably not all that important when you're guessing;-)
