Serial monitor showing "Connect to AC101 codec Failed!". [solved]

[souravlal]

The 'esp32 _midi_sampler' program was successfully uploaded to ESP32 audio-kit. But when I open the serial monitor it shows "Connect to AC101 codec Failed!".
Please help me out.

Is it the first time you are trying to use it? Do you have a picture of the Audio Kit?
I can recommend running I2C scanner to ensure the AC101 can be connected Wire.begin(33, 32);.
If that fails you can try a different pin setting: Wire.begin(18,23);

I've uploaded an update today which does support the ES8388

Oh, Thanks.
I have already bought the one with AC101.

@marcel-licence Does the ESP32 Audio-kit require a restart every time we need to load a new sample?This is the case with me.

A restart shouldn't be required. You should ensure that you have enough memory left (~4MB is available for all samples).
