It's the application that asks for the buffer size. Indeed. Probably the most interesting thing here is how Phonon is configured.... In theory going directly through pulse is best (via the xine-pulse plugin, or gstreamer-pulse pluging depending on your phonon backend), but it seems that one of the plugins (on your system at least) is not performing particularly well. I should say that I suspect it is the xine plugin. /me hates the whole concept of the xine backend in Phonon. I wish more effort had been put in to the *Qt supported* gstreamer version rather than spitting out the dummy but such is life.
