That's strange. I've upgrated my ubuntu from gutsy (7.10) to hardy (8.04), and I've gotten sound on flash (and skype also) working out-of-the-box. I'm using pulseaudio 0.9.10-1ubuntu1, flashplugin-nonfree 9.0.124.0ubuntu2 and firefox 3.0b5. I've posted a screenshot of PulseAudio Volume Control showing the Flash audio stream here: http://www.students.ic.unicamp.br/~ra016378/flash_with_pulse.png If you need me to collect some more info to try to debug the problem, I'm glad to help. -- Jo?o Paulo Rechi Vita MSc Computer Science Student Computer Engineer IC/UNICAMP
