OnQ Lyriq - "Whole House" button not working
We have an OnQ Lyriq system with 6 installed zones using high performance keypads. We've noticed recently that the 'whole house' button on all of the keypads has stopped working. Pressing the button on any of the keypads causes it to flash as expected, but the selected function (power on, change volume, select source, etc.) does not get propagated to any of the other 5 keypads. This behavior is consistent - none of them work. All of the other functions on the individual keypads work normally, volume, select source, on/off, mute, for all connected sound sources. Only the 'whole house' function is failing. I've tried killing power to the hub and all the keypads, but it didn't help.
I've had to replace the hub once before due to a power surge, and I'm suspecting this is another hub problem.
Thoughts? Has anyone seen this symptom before?
