Hi, you use `esp_err_t audio_hal_set_mute(audio_hal_handle_t audio_hal, bool mute);` can achieve the effect of mute. If you want no sound output, you can use `esp_err_t gpio_set_direction(gpio_num_t gpio_num, gpio_mode_t mode);` turns off...

`E (586) gpio: gpio_install_isr_service(412): GPIO isr service already installed ` is normal. You can ignore this log and use `esp_err_t audio_hal_set_mute(audio_hal_handle_t audio_hal, bool mute);` needs to contain es8388. h.

Dear bs-eng, I think you mean removing the noise floor. Under normal circumstances, `esp_err_t audio_hal_set_mute(audio_hal_handle_t audio_hal, bool mute);` can achieve this effect, and there is another way as you said,...

If line_ in is used as input, setting the gain to 0 is correct.

Hi @RaresCon Software solution reference: [bugfix/improve_es8311_i2c_stability](https://github.com/espressif/esp-adf/commit/8fc8a4a639851f3d2fba62145d511e954aa75069) Hardware solution: Add a 33pF capacitor and a 33Ω resistor low-pass filter to the CLK and SDA lines near the I2C pins of the...

Hi @RaresCon In terms of software, the ES8388 does not have registers for the I2C. Please try reducing the I2C frequency and adjusting the [glitch_ignore_cnt](https://github.com/espressif/esp-adf/blob/master/components/esp_peripherals/driver/i2c_bus/i2c_bus_v2.c#L120) parameter. If you have tried...

Hi @GCTechnology I have conducted multiple tests using the ESP32-LyraT development board, and the issue mentioned above did not occur on this board. I would like to know if your...

Hi @RaresCon @GCTechnology Any progress on the issue?

> [@ALToast](https://github.com/ALToast), should this schematic be used instead of LyraT-4.3's? I found this in the user guide for ES8388, which states that a resistor of 330 and cap of 2200pF,...
