I have cec-client running on my raspberry pi, and I'm able to switch between active sources HDMI 1 - 4 on my Sony TV with:
echo "tx 4F 82 10 00" | cec-client -s
echo "tx 4F 82 40 00" | cec-client -s
What I haven't been able to achieve is switching back to TV as active source. Since the TV normally has ID 0.0.0.0, I would expect the following command would do the trick, but no response from TV:
echo "tx 4F 82 00 00" | cec-client -s
4 = Recorder 1 (raspi)
F = Broadcast
82 = Active Source
00 00 = ID
Has anyone successfully done this pretty basic operation?
