I would try a different cable to rule out the possibility of a bad cable. You can get a cheap Monoprice for that exercise.

I2s cable not working with my DAC
I just received my new HALO MAY DAC and in trying to hook it up to my PS Audio Airlen’s I get no sound with the I2S connection. It works fine with a digital cable hook up. The same thing happens with my CD player trying to use the i2s connection. I’m befuddled.
