Can the HDMI port be used as an output for a NAA(Pi 4 or Mini PC Atom Z8350 CPU) connecting to a DAC?
Generally HDMI audio should work as long as there are required audio drivers. I don’t actively test this, as I don’t have any AVR or DAC with HDMI input. I could test it with my TV, but it is not part of my regular testing.
