Hi Phil, I've had that issue before. You might need to re-select your audio device from the Media menu before turning DSP on. I believe that in macos it would be Media > portaudio, unless you are using jack.
I am not sure why this error happens, but I guess it relates to the pd~ subprocess changing the saved settings.
