I got rid of the xcb_connection_has_error() by unsetting shell environment variable DISPLAY, which PuTTy was helpfully setting for me (for good reason in other circumstances).
The line os.environ["SDL_VIDEODRIVER"] = "dummy" still seems to be necessary. However, I still get no sound. I'll try the RPi forums and see what anyone can suggest there.
