Redirect Audio

[paulscottrobson]

I have some TTGO VGA32 1.1 boards, which are like the 1.2 except they don't have an audio pin. There are other pins on the board ; the most tempting is the clock pin on the mouse port, which is connected to GP26. I experimentally put a piezo buzzer here and changed i2s_audio_init() in the sound generator so it is i2s_set_dac_mode(I2S_DAC_CHANNEL_LEFT_EN); which should - I think - redirect audio through GP26 not GP25 ; it does not work. Is it possible to redirect it here (is it set for other use ?) or redirect it generally ? My ESP32 skills aren't that great :)

Thanks.
