fix mck_io_num

[apiel]

mck_io_num does not exist in i2s_pin_config_t

[pschatzmann]

How about using an actual ESP32 version. Why are you still using this old release ? An alternative is to make sure that you deactivate this only for releases < 2.0

[apiel]

I don't know, I just git clone and run the example. When removing this line it worked... How should I do to use the new release?

[pschatzmann]

Go to the Arduino Board Manager and install a recent ESP32 Release. The latest version is 2.0.6!

If you want to keep your PR, please correct it to

if ESP_IDF_VERSION > ESP_IDF_VERSION_VAL(4, 4, 0)

  KIT_LOGI("- mck_io_num: %d", pin_config.mck_io_num);

endif
