excuse the incompetence
I placed the script, as specified, for i2s
It works with "hifi Shield" but not an external DAC.
order pin seem right, does not use the MCLK.

Thank you

Hi,

I am going to connect I2S to other DAC.
I find I2S out seems unusual and got no sound even I updated /boot/boot.ini and "DAC enabled".
There are no ODROID DAC available on Audio out and only ODROID HDMI selected.

when I connect nothing to these pin and check with DMM. Result as follows:
PIN 4 I2S MCLK 1.628V
PIN 5 I2S LRCLK 5V
PIN 6 I2S SCLK 3.26V
PIN 7 I2S Data Out 5V

It is normal?

Show us your boot.ini file to find what's wrong.
