Please describe your issue in as much detail as possible:

I was glad to see the CEC support in 3.6 branch, but unfortunately it is still missing the most important (to me) function, which is waking the deck (with dock of course) from sleep simply by switching the TV to the right HDMI source. Every other device I have supports that - i.e Apple TV or PlayStation. I simply turn on the TV, select the source for signal and the device turns on automatically and starts sending the HDMI signal. The deck doesn’t wake up in this case.

Steps for reproducing this issue:

1. Have the deck docked and connected via dock to power and HDMI of the TV
2. Turn on the TV and select the deck HDMI source for input.
3. Observe the lack of HDMI signal (the deck is still in sleep mode)

I am experiencing the same issue. Interestingly, it DOES work in desktop mode. Only in gaming mode it's broken.
