I get similar behavior on Linux as well, no segfault though. The audio
plays through fine every time I call either play or playblocking. With
playblocking I see the same error message on the second play through.
Also this:

  octave:32> playblocking (player);
  octave:33> player
  error: audiorecorder: Error checking stream activity status
  error: called from:
