Hi Kevin,
The ‘socket used’ indication is a new feature of V1.5, so the colour change sounds normal.
The only thing I can think of that could be seen as an error message when touching on the sockets would be ‘This socket has no controls’ which appears whenever a socket is selected that does not have any controls available (i.e. any socket that doesn’t have a preamp or sample rate option).
Therefore I would suggest checking the following to work out where the ‘break’ has occurred:
Check the sample rates of the Dante equipment all match (48/96kHz).
Ensure all Dante patching is correct and connections have ticks in Dante Controller.
Make sure the address of the Dante card hasn’t changed – you mention using wireless control, and if the Control Network Bridge is on there is potential for an option card set to to have it’s address updated by a connected router (if DHCP is enabled).
Double patch the outputs being used for Dante to other sockets to check the audio.
If you’re still having problems, please contact us using https://support.allen-heath.com with more details on the setup and how you have everything connected.
Thanks,
Keith.
