Just with audio it is difficult enough, and I agree with you.
Adding in audio from a video (for a specialized DAC), I would love for that too, but as far as I know, that doesn’t exist. For the audio part of a video, i use the internal DAC inside the $1100 Panasonic 4k blu-ray player, which is quite good, not as good as an MU2 DAC for audio, but still quite good.
