user84430: I am trying to use the ESP8266 to output some audio, but I'm having trouble making it work. I downloaded the library ESP8266Audio and am testing one of the examples they have in the repo, namely streaming MP3 from HTTP, (link). There is nothing however outputted from the I2S pins, D1 and D2, but only from RX pin. I have a dual amplifier, so I need the analog signals, not the digital. So I want to ask if there is something extra I need to add in the program, or if I'm using the wrong pins. Any help is appreciated :)

user38721: There might be a built-in I2S module, but an I2S module does not output an analog signal. The ESPs have no DAC, so you definitely need additional hardware in form of a I2C-DAC/codec IC. There's no software solution.
