thanks for your reply.
You left MCLK open, other wired like here described: https://github.com/espressif/esp8266_mp3_decoder ?
I see all wires have signals, but i get only a noise.
I am not sure i compile it with the right parameters, i will try out other combinations with flash download tool.

Given ESP8266 don't supply MCLK (AFAIK) I put a 48 MHz external oscillator in the evaluation board. The value is suitable for asynchronous configuration but I am not totally sure that it was the case. I need more time to study the configuration in the MP3 project. Now I am working in reducing the RAM need.
