I'm not sure if I'm expecting too much here but here goes ...

My DVD player is connected by HDMI and when I press Play it switches itself on and thereby switches on the TV (Grundig Sydney 4xHDMI) which automatically selects the appropriate HDMI input.

Since I added the Raspberry Pi (set up as an XBMC) this function no longer works - even when the Pi is switched off. If the TV is off and the Pi is already switched on and then the DVD is activated, the TV fires up but shows the Pi screen.

Any ideas what is going on here?

Clarification

  • As long as the Pi is connected via HDMI to the TV, the DVD player cannot wake the TV at all.
  • It makes no difference whether the Pi is powered on or not.
  • If the Pi's HDMI cable is unplugged from the TV then the DVD can wake the TV.
  • Once the TV is active I can select either of the inputs manually.

By "even when the Pi is switched off" do you mean the power is plugged, or something else? –  goldilocks Feb 25 '13 at 15:47
    
@goldilocks - when the power is removed from the R-Pi but HDMI still connected –  paul Feb 25 '13 at 19:48
    
In that case, it is the same thing as if you had an HDMI cable with nothing on one end (or any completely unpowered device) and the other plugged into your TV, right? Implying the issue is with how the TV works... Same WRT when "the TV is off and the Pi is already switched on and then the DVD is activated" -- this implies the TV turns itself on but then cannot decide between two active inputs. Tell Grundig what it should do is detect which input activated it and then use that one. –  goldilocks Feb 25 '13 at 19:55
    
I now notice that, so long the Pi is plugged in (power on or not), the DVD cannot wake the TV at all. If I remove the Pi then the DVD does wake the TV :-( –  paul Feb 26 '13 at 19:09

Consider switching so that the HDMI-port in the tv currently connected to the DVD becomes the one connected to the Raspberry and vice versa. This might be a question of the TV only supporting HDMI-CEC on the first device found. –  Thorbjørn Ravn Andersen Apr 22 '13 at 21:36
