How is the DFPlayer Mini supposed to be started?

Then I eject the SD card, wait a while and put it back. After that the player works just fine. But sure the player should work with the card inserted before powering up, or have I missed something?

On forum.arduino.cc, someone suggested to add pullup or pulldown resistors to the pins. Which pins would benefit from them?
