I can use my Pi with cec-client to change the TV input source between HDMI1, HDMI2, etc. All works fine, with this sort of command:
echo "tx 2F:82:10:00" | cec-client RPI -s -d 1
Where "10:00" is the address to switch to for HDMI1 (1.0.0.0), "20:00" is the address for HDMI2 (2.0.0.0), etc.
My problem: I cannot for the life of me figure out how to switch to the TV tuner (address 0.0.0.0). The above command with "00:00" does nothing.
I've searched and tried things and nothing seems to work. (This is a Vizio TV). cec-client works great for everything EXCEPT changing the source to the TV's tuner at 0.0.0.0, which is a critical need for our application.
Help???
Thanks.
