Dear community, I've installed pd, version 0.43.0-4 on my ubuntu 12.04 machine (64 bit) from the repositorys. Unfortunately, I can't get sound out of it. First I'started qjackctl, and then PD. From the menue "Media" I choose "Jack". In qjackctl I can see, that system and puredata are connected. When I know click "Media", "test audio and midi" unfortunately nothing happens, it doesn't matter if the box DSP is choosen or not. I can also open some patches, but I dont know how to get sound of it. Am I missing something very simple? Sorry, but I can't find my mistake.
