Re: Releasing the TV before shutting down ?

Druck,

A "cec-client" you say ?   I'll have to look for it.

apt install cec-client

Thank you.    Joerg Walther posted a bit more extensive instructions to
install the utils, and as such that part went without a hitch.

You'll then need to find the commands change the source, which will depend
on your TV. Pages such as this may help

:-) It so happens I found the same page.

But alas, neither the "as" command nor the "tx" commands I tried caused the
TV to switch back to its own tuner.

Remark: the "scan" as well as the "standby 0" worked fine (meaning: the TV
does understand CEC)

Yesterday I didn't think of it, but today I'm going to switch my DVR on as
well (so the TV has two HDMI sources) and see if I can get the TV to switch
to the DVR and back- just to make sure the "swich to" command(s?) are
actually understood.
