Well, seems it does in most AV receiver makes, because the manufacturers
provide them mostly with one single power(ful) supply, there are some
Yamaha models with a separate (low) power supply just for the video
(HDMI-related) circuitry, they can achieve just 2-3W in standby with
HDMI-CEC... Anyway, it's an issue one shouldn't take for granted and
meet with decent skepticism, rather measure at the power outlet in the
given situation. The manufacturers are not likely to specify this in
their data sheets or manuals. Some models allow you to setup HDMI-CEC
only for the ARC from the TV and let power control or HDMI passthrough
disabled. But the latter two are also nice to have, unfortunately they
come at such cost...
