title: Set active source to TV with cec-client
body: <p>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:</p>
  
  <pre><code>echo "tx 4F 82 10 00" | cec-client -s
  echo "tx 4F 82 40 00" | cec-client -s
  </code></pre>
  
  <p>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:</p>
  
  <pre><code>echo "tx 4F 82 00 00" | cec-client -s
  </code></pre>
  
  <p>4 = Recorder 1 (raspi)</p>
  
  <p>F = Broadcast</p>
  
  <p>82 = Active Source</p>
  
  <p>00 00 = ID</p>
  
  <p>Has anyone successfully done this pretty basic operation?</p>
