audio triggers disabled?
 

I searched the forum and all I can find are threads about people using them. I don't see anyone saying they are disabled but I can't get them to work. I create the trigger and I can hear the alert in the audio trigger window. When the trigger comes up in the chat window nothing happens though.

yes, audio triggers via the ingame interface are disabled (along with map, compass, etc)

There are third-party log parsers such as Gamtexttriggers to set up audio triggers. These are okay to use since they only read the log file and do not interact with the client.
