it was weird I heard a friend talking perfectly and the next day I don't even hear the other mic- no static nothing- just empty space..
running 10.4.9
dual 2.5ghz G5
3.5 Gigs of RAM
using a USB Logitech headset
set up properly in system preferences and skype preferences
hopefully going back to Skype 2.5 will solve this!
btw I've used Echo123 it works
