Hi @sun-xiangyu! Please be aware that (1) the following suggestions are generated by a bot and haven't been fact-checked by Espressif Systems, (2) burning eFuses and enabling security features are irreversible operations and can damage your ESP32 device. We hope that this message will help you until an Espressif Engineer looks at your issue.

Thank you for providing detailed logs and context. The error message:

E (xxxx) i2c.master: I2C transaction unexpected nack detected
E (xxxx) I2C_If: Fail to write to dev 30
...
E (xxxx) ES8311: Open fail

indicates that the ESP32-S3-Korvo-1 board is failing to communicate with the ES8311 audio codec over I2C (device address 0x30). This is a hardware-level NACK (Not Acknowledge) from the I2C device, which usually means the device is not responding to the ESP32-S3's requests.

Based on the official documentation and hardware references, here are the most likely causes and recommended steps:

1. Check Hardware Connections

• The ES8311 codec is connected to the ESP32-S3 via I2C and I2S. If the I2C lines (SDA/SCL) are not properly connected, or if there is a bad solder joint or loose cable, the device will not respond and you will see NACK errors.
• Make sure the ESP32-S3-Korvo-1 board is assembled correctly and that the main board and sub board are firmly connected via the FPC cable. Double-check the I2C lines to the ES8311 chip as shown in the hardware reference.

2. Power Supply

• Ensure the board is properly powered. The ES8311 requires a stable 3.3V supply. If the power is unstable or missing, the codec will not respond on I2C.

3. I2C Address

• The error log shows attempts to communicate with device address 0x30, which matches the ES8311 default I2C address. This is correct for the ESP32-S3-Korvo-1 board as per the documentation.

4. Board Version and Example Compatibility

• Make sure you are using the correct example and configuration for your board. The audio example is compatible with ESP32-S3-Korvo-1, and you should use the provided sdkconfig.bsp.esp32_s3_korvo_1 file as you did. If you have made any changes to the hardware or configuration, revert to the defaults and try again.

5. Check for Physical Damage

• Inspect the ES8311 chip and surrounding components for any visible damage.

6. Other Troubleshooting

• If you have access to an oscilloscope or logic analyzer, check the I2C lines for activity and confirm that the ES8311 is pulling the lines as expected.
• Try resetting the board and re-flashing the firmware.
• If you have another ESP32-S3-Korvo-1 board, try running the same example to rule out a hardware fault.

7. Reference to Known Issues

• The I2S ES8311 example troubleshooting guide suggests checking the PA (Power Amplifier) control pin, but your error occurs before audio output, so focus on I2C connectivity first.

---

Summary:
The error is almost certainly due to a hardware connection or power issue between the ESP32-S3 and the ES8311 codec. Please check the FPC cable, I2C lines, and power supply to the codec. If all hardware appears correct, try the example on another board if possible. If the issue persists, please provide photos of your hardware setup for further assistance.

After modifying the default setting of idf_component.yaml file, it can work.
