DfPlayer Mini Noise 9V

Currently that is my setup with a Arduino Nano + DFPlayer Mini minus the resistor. If I power the Arduino via USB cable everything is working fine. If I power the Arduino with a 9V battery, the DFPlayer does not receive the the signal to play the music and I get this noise ... sp=sharing on the speaker. What could be the problem?
Thank you.
