Pulseaudio does not come automatically with Intrepid Ibex I believe. I do not see the device chooser in the top right corner of the screen, like it used to be with Hardy Heron. In order to be useful however, I would like to provide some debug output so that if the problem is located within wine, that it can be fixed for an upcoming version. If there are any commands I should run and provide the output, please mention them.
