Hi everyone,
I've been trying to install pd-extended on a brand new (well, I've just bought it) Asus Eeepc 901 running Mint12. When I sudo

aptitude search pd-

I get lots of libraries (pd-ext13, pd-utils…) but nothing like pd-extended. Is that normal ?

Hello.
Maybe you have not yet installed the multimedia repositories.
If your linux mint is debian-based: first, you should install the debian-multimedia-keyring (search for it using aptitude or synaptic), then modify as super user the file /etc/apt/sources.list (or add a new repository using synaptic, it's equivalent) A new line in /etc/apt/sources.list should appear:

deb http://www.debian-multimedia.org/ wheezy main non-free

Note: instead of "wheezy" you may find "squeeze".
After that, you should update the list of packages, by synaptic or typing (as super user):
# aptitude update

Then pd-extended may appear with a 'p' at the left if it's not installed yet when you search for it
In my case:

Thanks for your help. My Mint seems to be Ubuntu based, though. And if I do see a "debian-keyring", no "debian-multimedia-keyring" at all.

So I installed from http://autobuild.puredata.info/auto-build/latest/Pd-0.43.1-extended-ubuntu-oneiric-i386.deb and it seems to work (that means I tested audio and heard a "beeep"). Now it's very late in France so I wish you a good night. I can go to sleep, I'll make deeper tests tomorrow !
