Unpredictable Annuciation

Looking for an answer as to what might be causing the unpredictable annuciation of an audio source for one particular zone. All is working well throughout the home which includes lighting control, touchscreens, and 3 matrix switchers with multiple zones of audio, etc.. We have a NEO DLT keypad with a button programmed to toggle between audio sources in the "Gameroom" (local, analog 1(home theater), and Tuner 1. This DLT kepad works as programmed. However, one of the audio sources (Home Theater) for this zone is being triggered by various other inputs throughout the home. Example, when a keypad is pressed to turn on a lighting load in another room, then the audio source for the "Gameroom" zone annunciates "Home Theater" for no reason? A review of the programming of the amp, marpa file, and cbus files reveals nothing. All addresses are assigned correctly it appears. Not having this issue with any other audio zone locations or audio sources. The Audio Application was used for all audio group addresses and all lighting group addresses are under the Lighting Application. Any suggestions how to troubleshoot?

 

The very first step is to use the Diagnostic Utility to look at the C-Bus network traffic when the misbehaviour occurs. This can be quite revealing as it can point to which unit is sending the message causing the unintended behaviour to occur.
