You need one of the newer autobuilds from http://autobuild.puredata.info/auto-build/.

I'm using PD-Extended 0.40.3.  Currently there is a bug with jack and pulseaudio and you need to kill pulse for best results.  Just hit Atl+F2 and type "killall pulseaudio" then, when your done with jack turn pulse back on with Alt+F2 "pulseaudio".  Well, at least thats what I need to do to get it to work correctly with my external soundcard ... so yeah, post a bug report if things go crazy for you.

Hello!

Does someone knows how to install puredata extended on Ubuntu Hardy Heron?

I tried Pd-0.39.3-extended-debian-testing-i386.deb, from 
http://puredata.info/downloads, and I got "Error: Dependency is not 
satisfiable: libflac7"

I tried Pd-0.39.3-extended-rc5-debian-stable-i386.deb, from 
http://at.or.at/hans/pd/installers-0.39.3-extended-rc5.html, and I got 
"Error: Dependency is not satisfiable: libflac7" as well.

I used to work with it on Gutsy, but now with Hardy Heron how can I do?

Thanks a lot for your help.
