It tends to be unidirectional. The status or existence of any audio sink on the monitor end is unknown. The OS knows whether a bus termination has been plugged to an HDMI (or DP or VGA) connector. It can then route a video signal to the load, knowing that it's not creating RF emissions by the cable end being open. But audio carriage on the cable, there is no mechanism I'm aware of, which commonly can talk back and relay information about whether there are speakers or an audio sink. That's more or less best effort (works, if you have speakers, otherwise the bytes go into the bucket). Since there are hardly any questions about Dolby, I would guess that most people consume movie content, with 7.1 LPCM as the audio track, rather than Dolby flavors of coding. Paul
