Walkie Talkies buffers but fails to playback #8

Hey there. I did build a raspberry pi powered WIFI-enabled voice messaging box:

Now the cool thing about the ESP32 is that it does not have to boot up as long as a Pi. So I wanted to try out your project.

I was testing your esp32_audio samples and I could play the sample.wav file and I could record some data into a i2s.raw file using the node server. I could not replay the recorded file but it had a bunch of hex-values in it. So the wiring should be correct.

I did setup two ESP32 with I2S Mems mic and DAC. They "see" each other both using ESPNow and WIFI but after buffering nothing happens.

My IP Address is: 192.168.1.121
My MAC Address is: 7C:9E:BD:46:56:C0

So I am currently at a loss on how to get this to work. Maybe you have an idea on how to debug my setup. Kind regards and thanks for sharing your knowledge with the community!
