HDMI I2S output from CD80-StreamUnlimited

Hi,
I wanted to make hdmi-i2s output from project ds cd player with StreamUnlimited cd80 board.
I bought i2s to hdmi board.
I conected 5pin ribbon to folowing points. Marked with red dots on schematic and red points on board.
I measured signal with scope and was present. not so great on output as input but present.
But no lock trought hdmi i2s input on smsl m400dac. I tried dac before on computer with pinkfaud i2s hdmi card and dac was playing ok.
I2s to hdmi card has also SDA and SCL pins which were not connected.
Any idea what can be the reason?
