I have the War Drums sound chosen to play anytime there's a rare detected, targetted, mouse-over, and originally I had it sending to 'Master' sound channel, but today I noticed it is no longer playing the sound. It was fine before pre-patch. Could something be up? I tried toggling the settings, and changing it to general 'Sound' channel to see if that helps.

I can't reproduce it not playing the sound. Could you try setting a different sound and seeing if that makes a difference?

You can test it without having to go find a rare by going into the SilverDragon options and selecting the "Outputs" menu, then going down to the "Test it!" section -- clicking the buttons there will fake you seeing various rares.

Darn you are right, now I can't reproduce it. Must've been gremlins in the machine. If it happens again I'll see if I can troubleshoot better. Thanks for the testing tip!
