Changing i2s sample rate dynamically

[AntonioTesta]

Does anybody know how to change the i2s sample rate during execution time ? The .sample_rate bellow i2s_config_t i2s_config = ... accepts only constants, so there is no way to change that value during the program execution. Any help will be appreciated. Thanks

i2s has following API:
esp_err_t i2s_stream_set_clk(audio_element_handle_t i2s_stream, int rate, int bits, int ch);

the rate setting is the sample_rate settings, please make sure the input data rate and I2S sample rate is matched or else the tone will listen to be strange
