I would like to add that this behavior is only evident when playing a flash video via the browser. But if I play a video via ffplayer, then after the end of the video, pulseaudio goes back to consuming almost 0% of cpu. So, is it possible that the flash plugin is not closing the audio file descriptor, so pulseaudio keeps polling and finding nothing? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
