Hello, I just downloaded and flashed Volumio on my RPi 2 mod B.
I bought an ES9018 DAC from Aliexpress with I2S interface, connected all pins, and select from settings “generic I2S DAC”.

The FFT:
And the volume control seems not to work. Any idea of the problem?
P.S. if there is anything playing, i see nothing on the oscilloscope.
