I'm fairly sure that the 'ear-protection' drops in volume have been
while running leanfront on the TV's hardware under its Android OS, but
the info above was copied from the TV user's manual (and I could quote
it in 18 other languages).
leanfront gets its content via ethernet, but the TV also has 3 HDMI
inputs as well as DVB and network sources. One HDMI input comes from
the nVidia card in the Myth FE/BE Fedora box and can display content
from that by mythfrontend, mpv, vlc, browsers, terminals etc.
I find it easy to choose what I'm using, but it wouldn't be a
family-friendly setup. It's even worse when feeding an HDMI input from
a FireStick, with two different remotes in action. I don't usually do
that now.
Whatever, I think the ear-protection experience is an Android OS
feature. The popup display shows a headphone symbol; it actually shows
TV-audio gain rather than absolute output level.
Sorry for the confusion.
John
