Program for RPi to connect HDMI I2S Dac

Hi. Did anyone share your experience any program can support using RPi to connect HDMI I2S DAC?

Try reading up here, but I am not sure if all units are sold. I did try to get one working but didn’t use the HDMI I2S interface as my DAC doesn’t have that. Mine is Soekris DAM 1021

Keep in mind that there is no standard I2S HDMI wiring, different DAC vendors use different pinouts, it’s not just a matter of software. Audiophonics have announced a Pi-based streamer that they claim can be configured for different HDMI I2S DACs. I’ve not tried it, just passing along.
