Hey qole,
thanks so much for your help. This is probably easy but I'm a nub.

I'd like to try to re-install the portaudio v19 as the guide says, but I can't seem to find the directory audacity-src-1.2.x/lib-src/portaudio-v19/

I'm looking using the debian terminal, and even then I am unsure where that directory is. I tried looking for it with a which and find command, but can't find it. I searched through a lot of the directories. is there a better command that would locate it? Or do you know where it would be?
