Well, I wanted to describe some of the relatively minor sound problems I’ve encountered after upgrading to Hardy, while giving some kind of an overview of how things are with audio and Linux and why are we seeing problems with this release, but this article does a much better job at it then I could.
Very briefly, the solution for my audio problems was to set all the options to “PulseAudio Sound Server” in the “Sound Preferences” administration applet, and install the “libflashsupport” package.
Update: Another class of applications that is affected by the switch to PulseAudio is those appications that use the SDL library. Thos can be configured to use PulseAudio exclusively by installing the “libsdl1.2debian-pulseaudio” package and making sure no other “libsdl1.2debian-*” package is installed.
