I'd love to know if someone had this problem and find a fix:

Im using ubuntu studio 12.04 (with QjackCtl) and eveytime i start pd-extended (but not puredata) all other audio stops. it looks like pd takes over the whole audio. playing around with jack didnt much help

Does anyone had this thing?
Many thanks in advance,
Danwe

Same Crash here, on xubuntu 13.04 without the ubuntu studio.
