Problems with HDMI audio passthrough output limitation

Can't I export 192khz 24bit audio such as DTS-HD, Dolby ATMOS, True HD, ... on an M1 Mac with HDMI??? Really????

HDMI 2.0 support seems to be enough for the specs, but I don't know why they don't support audio passthrough. You can't export next-generation audio such as ATMOS even when you're watching Netflix on Safari or watching videos on the Apple TV app.

Please release the Audio Output limit.
