[PD] PD with Ubuntu Karmic - no sound

Sound with lots of latency is better than no sound at all. Here's how
I see it now:
- pd currently doesn't make sound on Fedora/Debian/Ubuntu without
changing settings
- newbies are screwed, no sound output
- advanced users already setup their own audio
So if we use padsp by default, we get this, which seems preferrable to
me:
- pd makes sound on Fedora/Debian/Ubuntu without changing settings
- newbies get sound with lots of latency
- advanced users already setup their own audio
Even better, you could get sound from Pd and other apps at the same
time. If there is a way to get to the second status without big
latency, that would be the best. 'padsp' is the only trick I know of,
I haven't tried pasuspender tho.

If you are not part of the solution, you are part of the problem.
