I2S HDMI output Hat for RPi, Ropeee compatible?

This topic has been covered one year ago here, but with no straightforward answer and there is maybe some new hardware.

I seek for a hat with a HDMI I2S output for my Audio GD R7. Of course Ropeee compatible, with no or little tweaking, or documented tweaking.

Does someone have any insight about this ?

I’ve found https://www.audiophonics.fr/en/dac-and-interfaces-for-raspberry-pi/ak4118-digital-interface-spdif-i2s-hdmi-lvds-raspberry-pi-3-pi-4-p-14255.html will this interface work out of the box with Ropeee, selectionning which option ?

I2S LVDS is not compatible with Audio-GD I2S HDMI (http://www.audio-gd.com/R2R/DI20/HDMI1.jpg) My quest continue…

Pi2AES seems also output I2S LVDS, but this is unclear…

For those interested, I ended up with a matrix-audio-x-spdif-2 (Matrix Audio X-SPDIF 2 Review) which gives me an excellent I2S output from the USB output of Ropieee
