Hi Marcel,

My ESP32-devkit-board has just arrived and wanted to see what your project does.
After flashing my devkit-board i see:

Connect to AC101 codec... Failed!
Failed!
Failed!
...

I read a post somewhere about that recently the exact used chips were changed. Just leaving this information here for others...
I've not looked into a solution/workaround.

greetings, Sander

Running into an issue where PSRAM is getting all used up and is stuck in a boot loop. see attached log boot log.

Board: ESP32 Audio Kit V2.2 A247

I edited "board_audio_kit_es8388.h" according to what I could figure out from i2c scanner and what I could find:

#define ES8388_CFG_I2C 2
#define ES8388_CFG_I2S 7

#elif ES8388_CFG_I2C==2
#define ES8388_PIN_SDA 33
#define ES8388_PIN_SCL 32

//I added new option 7 for this version ESP32 Audio Kit V2.2 A247
#elif ES8388_CFG_I2S==7
#define ES8388_PIN_DOUT 35 //DATA
#define ES8388_PIN_DIN 26 //DATA_RX
#define ES8388_PIN_LRCK 25 //WS
#define ES8388_PIN_SCLK 27 //BCK
#define ES8388_PIN_MCLK 0 //MCK

With boot debugging I just see a bunch of this:
`[������m�um����2-hal-cpu.c:211] setCpuFrequencyMhz(): PLL: 480 / 2 = 240 Mhz, APB: 80000000 Hz
[ 842][D][esp32-hal-psram.c:84] psramInit(): PSRAM enabled

@marcel-licence Not sure how much you can help in this regard, but cannot get this Audio Kit V2.2 A247 to sound like your video. This thing just sounds terrible and no matter trying to switch to input rather than mic, mic stays engaged and has all of these electronic artifacts. Wonder if these new ES8388 is the issue. Not sure what to do here. A lot of floor noise and electronic interference of some sort.
