Disconnected, why?

[Theiamania]

Hi,

I have a Rpi 3 Model B with cecutils and I can control my cec devices using the console, but not with node-red-contrib-cec.

My config of cec node is:

And this produces this errors:

ERROR:   [            3086]	AllocateLogicalAddresses - failed to allocate device '3', type 'audio system'
ERROR:   [            3086]	failed to find a free logical address for the client
ERROR:   [            3086]	failed to register the new CEC client - cannot allocate the requested device types
ERROR:   [            3086]	failed to register a CEC client

When I leave blank "HDMI Port" field (as recommended in the help info) it causes a warning before deploy:

And I have same errors, but with the error number 2609.

All nodes appears always as Disconnected and I cannot send/receive anything.

Can anyone help me?
