Seen several posts regarding the loss of audio from third-party USB webcams after installing 10.4.10. I can confirm this on my Logitech Ultra Vision camera. Video works fine, but there is no audio (the camera's mic isn't even listed in iChat). I've posted a bug report to Apple. Anyone else have this specific problem? If so, post here so I can refer Apple to this thread. Also, there is a new thread on Apple's forums at http://discussions.apple.com/thread.jspa?messageID=4788992#4788992 regarding this issue. Thanks!
