CEC adaptor couldn't initilise

Hi there,

I’m trying to get CEC to work on my Vero 4k with several different HDMI cables. The closest I get is a:

Pulse-Eight CEC apaptor
CEC adaptor couldn’t initialise
Please check your settings

pop-up error box at the exact moment I press an arrow key on my Pioneer LX-76 AVR.

Running /usr/osmc/bin/cec-client from ssh shows that it fails to to find a free logical address for the client:

Any ideas?

Also it would be nice to know which cable (markings) was included with the Vero 4k as I only later discovered that they wouldn’t work with CEC and it’s in a pile with my other HDMI cables.

Thanks.

Hello

You can’t run cec-client while Kodi is running.
Did you stop Kodi first?

System log should show some information.
Make sure all cables (between Vero 4K; AVR and TV) support CEC.

No, I hadn’t stopped Kodi, but I just did and now I get what looks like an identical error:

What can I look for in the system log?

Make sure all cables (between Vero 4K; AVR and TV) support CEC.

My Pioneer LX-76 AVR supports CEC so I’m assuming I only need a compatible cable between that and the Vero 4k. Which HDMI cable was included with the Vero 4k? Are they ‘Ching Tai High Speed’ with ‘jce’ on the connector? I only found out later they don’t support CEC and I’d like to label it as such.

Hi,

Sorry for the slow reply.

There seems to be the problem.

The CEC bus only supports a limited number of roles within the CEC bus, and only a limited number of devices can take each role. If this is correct, then disconnecting other peripherals from the TV / AVR should resolve the problem. I understand this isn’t a fix but it would be good to test that.

It might help to change the type of device that Vero 4K advertises itself as. See Vero2 CEC error message - #13 by makk509 for some more information.

The included cable is just a cheap and cheerful 1M cable to get people started if they don’t have a spare.

Cheers

Sam

Finally fixed this problem! I changed my cables out for CEC compatible ones (from Audioquest, who tell me all their cables are CEC compatible, although many other cheaper cables are too of course). After the latest update the pop-up:

Pulse-Eight CEC apaptor
CEC adaptor couldn’t initialise
Please check your settings

stopped appearing. I still had some trouble getting CEC control working as it turns out my Pioneer LX-76 receiver doesn’t fully support CEC.

Reading the ‘Control with HDMI function’ part of the manual (same passage as for LX-86), it sounds like it can be controlled by a CEC component but not control another CEC component, which is what I wanted.

Thankfully my TV is CEC compatible and so I ended up associating the TVs remote codes with the Vero and now I’m happily -1 remote.

Here’s my current output for reference (including one tv right cursor press that arrives at the Vero via CEC):
