When I plug my Raspberry Pi to my TV (which supports SimpLink, or respectively CEC) the TV automatically turns on from standby. This is due to the fact that the Raspberry Pi also supports CEC: http://www.raspberrypi.org/archives/1839

I would like to see this working with my HTPC aswell. It runs Debian Wheezy - the HDMI-connector is on a ASUS P8H77-I-board.

How can I

  1. check, if CEC is supported by my mainboard?
  2. make CEC work if it's supported?

Based on the specifications at the link you provided, I don't believe this motherboard has CEC support. It's a fairly new standard, especially to the PC world..

You might try looking at http://www.pulse-eight.com/store/products/104-usb-hdmi-cec-adapter.aspx for an alternate solution. I haven't tried the device as of yet, but it is an intriguing looking device.

  • thank you! After spending some hours on research, this was also my conclusion. I will contact ASUS to ask them if there is a way to make CEC work anyway. Do you have a clue if the usb-hdmi-cec adapter supports switching on the TV-screen from standby? – Marcel Jan 5 '13 at 12:30

    From everything I understand, the adapter should support just about anything that the CEC standard supports which does include standby switching as you have described. – Rob Gibson Jan 5 '13 at 17:24
