CEC not working at all

[raspberry_pd]

I think I was reading on Pulse-Eight that some HDMI cables are made without the CEC wire to cut costs or something. That could be a problem. Try another HDMI cable if you can find one.

I've never used cec-config to get CEC working. I may have just been lucky in testing two LGs and one Sony that just happen to support CEC.

Most feedback I've heard about Samsung's and CEC with the Raspi is positive so it's a shame this is happening for you. Your unit is reasonably new and does support "Anynet+ (HDMI-CEC)" according to the specs on the Samsung site.

Are you aware that CEC is known as Anynet in Samsung lingo? I have a slight suspicion you might be searching the normal list of ports on most TVs, where both Sony and LG (in my case) do not necessarily classify CEC connections or devices under the normal devices list.

For example, the device list on your TV could well be something like:

HDMI 1
HDMI 2
HDMI 3
PC (RGB)
USB
Component (Y/Pb/Pr)
Composite (AV)

but that doesn't mean you will see anything with the phrase "CEC" or the "Xbian" label the CEC adaptor in Xbian uses.

Also have another look at your manual on pages 29 -31

as there are some troubleshooting guides there.

If you're still out of luck, try ensuring the CEC adaptor settings in XBMC are all default, reboot and take a copy of your xmbc.log then paste it somewhere we can take a look at it. AFAIK the CEC adaptor attempts to set itself up during or shortly after boot. This may explain why you do not see any notices in the log during enabling or disabling but does not necessarily mean there's no CEC data in the xbmc.log
