Set active source to TV with cec-client

Question

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?

Answer 1

try this: echo "as" | cec-client -s
