Good evening (as it is in northern france). It's never a good idea when Yum or Apt wants to remove half the operating system to just say yes, when you want to remove a package. All you need to remove in the case of pulseaudio is the package "alsa-plugins-pulseaudio". If you are using KDE, this should also remove the KDE stuff for pulseaudio. I see that you are using VLC, and that uses SDL stuff, so you also need to add a line to /home/user/.bashrc, as below. unset SDL_AUDIODRIVER. Adding that line doesn't appear to affect playing DVD's though, as my DVD's play fine without that line. I'll come back to the libx264 problems on your "updates" thread. Al the best, and keep on trucking. Nigel. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
