I am very new to HDMI-CEC. I have a Pi3 and a Pi2 connected to a TV's two HDMI ports. If I run:

echo scan | cec-client -s -d 1`

I get the following output:

OpenELEC:~ # echo scan | cec-client -s -d 1
opening a connection to the CEC adapter...
requesting CEC bus information ...
CEC bus information
===================
device #0: TV
address:       0.0.0.0
active source: no
vendor:        Toshiba
osd string:    TV
CEC version:   1.4
power status:  on
language:      eng


device #1: Recorder 1
address:       1.0.0.0
active source: no
vendor:        Toshiba
osd string:    CECTester
CEC version:   1.4
power status:  on
language:      eng


currently active source: unknown (-1)
OpenELEC:~ # 

Two questions:

  1. Why can't CEC detect what is the currently active input?
  2. Why isn't the second Pi being detected (which I would expect to be 2.0.0.0)?
  • I have the exact same issue. I was messing with it this morning trying to figure out how to hack a way to infer the active source. I could not figure it out. My TV is a magnavox, for what that’s worth. – hepcat72 Apr 1 at 15:06
