cannot hear but people hear me. recent problem

[lidocaine]

I was in a raid today and vent was working fine, but all of a sudden I couldn't hear anyone. I can see green lights lighting up but I can't hear anyone. They report they can hear me. I've tried everything including:
-trying other vents to make sure its not just that one
-checking input/output settings
-sound settings
-changing the outbound to built in speakers in vent settings
-changing outbound to built in speakers in mac preferences
-deleting and reinstalling ventrilo
-creating a new vent name which would in turn default all my settings
-completely unplugging my headphones to just try to hear in vent

Now the really weird thing is on settings when I go to test...and I do a mic test I can hear myself fine...and the playback plays back to me fine. When I connect to or disconnect from server, I can hear the sounds. So I AM getting ventrilo sound, just not sound from other people. I've tried other channels, other vent servers, and reinstalling the program altogether. I'm still getting game sound through my headphones, computer sounds and even vent sounds when I connect/reconnect/swap channels/test my mic. This is bizzare! Please help as I have a raid soon!

on vent main window at bottom, is 'mute sound' box checked?
