Alarms Not Audible. PLEASE HELP!
We have 4 control rooms in our plant and each control room has at least 3 nodes. One control has lost all audible alarms. The alarms still show up in the alarm list but none of them are audible. There is NO problem in any of the other control rooms in the plant. It is only isolated to one room. All of the sounds are up on the computer, we can get sound from other applications. What could be causing this?
