[PD] PD with Ubuntu Karmic - no sound

The problem is getting things working for newbies. This has never
worked for me, but I haven't tried Karmic yet:
- install default Ubuntu setup
- install puredata.deb or pd-extended.deb
- launch pd using the GNOME menu item
- then check sound
This works on Mac OS X and Windows. I am guessing that you don't run
pulseaudio, so that is a non-default config. I still think a crappy
working config is a better default than a non-working config.
