Add hdmi_ignore_cec=1 to /boot/config.txt

I thought CEC doesn't do anything anyway unless running something like XBMC. But I have both a Pi and Ubuntu Linux on my desktop PC connected to my HDTV, so the Pi does not actually turn my TV on/off. And the only time my Pi pays any attention to my TV remote is when running Raspbmc.

Hi,

Thanks for the reply.

I have tried that command in the config file but it didn't make any difference. I'll give it another go in case I made a mistake.

If I boot my RPI it will turn the TV (Samsung) on.

The reason I want to turn CEC off is that the RPI is connected to my AV amp and when I turn that on with the RPI active it will switch to the RPI output regardless of what else is running through the amp.

It's no major problem just thought if there was an easy way of turning it off CEC I'd give it ago.

Cheers.

Hi,

Just retried the hdmi_ignore_cec=1 command in config.txt and that has done the trick! Must have made a mistake previously.

Thanks efflandt.

Cheers.
