DAC Write equivalent on i2s

[pikkuri14]

I used built-in esp32 DAC to generate 8bit sample audio, and the audio quite bad. I was planning on using External DAC (maybe PCM5102). I used dac_output_voltage(DAC_CHANNEL_1, 8bitsample) on my program. how can I write that to the external i2s DAC. I dont use i2s ADC input like on the example.

Please use the functionality of this library as described in the Wiki and the examples.

dac_output_voltage is neither part of my functionality nor should it be used for audio!
