Running i2s_adc_dac example on ESP-32 LyraT

[loganesp32]

Hi,

I 'm trying to run i2s_adc_dac example project, which is actually from esp-idf example under peripherals.
I ran it on ESP-32 LyraT ver 4.3 but cannot hear any sound via speaker even though the logs is saying recording , playing .
FYI, I can hear sound for other project( play_mp3) ADF example project. So speaker on the board was connected well.
In the readme.md of example(i2s_adc_dac), below hardware connection info was provided.

|hardware|module|GPIO|
|:---:|:---:|:---:|
|Microphone|ADC1_CH0|GPIO36|
|speaker(R)|DAC1|GPIO25|


It seems that the Lyrat board microphone, speaker differ from above info.
Where should I change above GPIO number in i2s_adc_dac example project for testing it on Lyrat?

thanks
Logan
