I think this is because > PortAudio uses ALSA directly... </div>This shouldn't be a problem as alsa can be directed to pulseaudio. I'm going to hazard a guess and say that Ubuntu probably hasn't included Kevin Kofler's patches in their portaudio package that makes it play nice with the alsa->pulse plugin? You should look in the Fedora or Mandriva portaudio packages for this patch. I'm not sure if it's gone upstream. <a href="http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/portaudio/current/SOURCES/portaudio-19-alsa_pulse.patch?revision=313993&view=markup" target="_blank">http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/portaudio/current/SOURCES/portaudio-19-alsa_pulse.patch?revision=313993&view=markup</a> With this patch applied, you app should work nicely with the following pipeline: App -> PortAudio -> Alsa -> Pulse -> Sound H/W -> Ears -> Brain <div class="Ih2E3d"> > I'd admit that I don't know much about audio playback and sound > architecture...
