Sound do not alert after upgrade to 3.0rc3


Recently we upgrade our Nagios to 3.0rc3. Everything is fine except sound is not shouting now.
We have tested by browse the nagio report service on different machines. All machine do not shout the alert sound. Is there any new plugin/software/config we need to check? Thanks!


We use IEwatch (an IE plugin to analysis each webpage’s HTTP request) . When critical status display, follow request return 404. What is it?

I believe it is something related with ActiveX, which it is required to play the WAV file. Isn’t it?
