I want to use dfplayer modules speaker output to connect to SIM800L MIC IN Pins. Can this being done? How to connect it? In other words Instead of a MIC input on SIM800L module, I use the sound out of the dfplayer module. Please see the attached file.

What is the reason for the noise? How can I fix the noise? Can you guide me by schematic?
