I2C and I2S at the same time problem

[RaresCon]

I know I am posting something about ADF in the IDF forum, but I suspect that this problem may not be related to ADF itself. I am using the latest ESP-ADF with a custom ES8388 codec board (PCBArtists) and ESP32-WROOM-32D (MCLK on GPIO3/RX0). I have successfully added a custom board for this setup and the A2DP Sink example is working almost fine, meaning that I can hear everything coming from ESP32, but I can not change the volume from ES8388, using the `audio_hal_set_volume` like functions, because the ES8388 always returns I2C Hardware NACK for any I2C command sent to it after the I2S stream is initialized and used, even though the codec should be able to receive and execute I2C commands while decoding I2S streams, because LyraT boards do not have this problem. I have checked the connections and everything seems fine, as all writes to the ES8388 at initialization work just fine and I don't get any I2C errors.

Pins used for I2C are GPIO22/SDA, GPIO23/SCL. The I2S pins are GPIO5/BCK, GPIO18/WS, GPIO19/DIN, GPIO21/DOUT.

If you have any ideas on this matter, I am happy to try out any changes to the code or to the setup.

I hope you all have happy holidays!
