Hello, hope someone knows how to fix this:

After I used once Jack in Pd, the default audio driver was set to jack. And now If I change the audio driver back to portaudio manually by clicking (cuz I'm not using jack), Pd will crash immediately. Is it possible to set the default audio driver back to portaudio? (I've tried already re-install Pd, delete Jack, open in command lines and adding the flag……..)

Would be great if someone can help !!!! Thanks!

It may not work, but, have you tried to remove the pd config file?
Mine, on linux, is ".pdextended" and is located on the home folder.

Thanks it works! (a bit different though: I delete the ".pdextended.default.plist")

Perfect, I'm glad to know you solved it.
