Thanks tim. ( I realize that the jack issue is separate, I just wanted 
replies to focus on pd and not jack -- (so they wouldn't say: "check 
jack!"))

It's kind of a pain to hear clicks. I've reduced them somewhat by 
starting pd with no audio capture. Don't know why that would be since 
I'm not using that facility.
