I recently upgraded to 13.10 and tried to create an audio CD. The application I tried to use was Brasero, since I think that is the one I had used successfully before the upgrade. But it complains that it needs a plugin to decode mp3s. Is there some package I need to install? And by the way, the sticky post at the top of this forum is obsolete and should be deleted. It says to add medibuntu.org as a repository, but their website says it is defunct.
