What OS? What sound device? What steps did you do to make it happen? etc etc etc

If it's on macOS, this can happen after putting the machine to sleep and waking it up. It's a warning that the current Portaudio stream was closed which can also happen when a connected device is unplugged. Previous to 0.49, Pd simply hard froze when this happened...
