hello guys , i have DF player module

i use the arduino example code of DF player , i encounter a very strange problem

when i connect the DF player and upload code everyting works perfect !!
but when i disconnect the arduino and plug the power back again

The DF begin to output a very bad sound , so i try to unplug wires then plug it again for troubleshooting , after a while is start working again , but still the same problem if i pull the power then get it back again still i get crappy noise !!

The grounds of all components (Arduino, DF player, power supply) should be connected together properly. A common ground is essential for proper operation, and not having it can cause noise issues.
