Roy Castle Centre
When our satellite office joins the conference there is a squeaking noise when somebody speaks. This can be heard at both ends. The office leaves the conference and rejoins and audio is normal.The office is setup thus:Logitech QuickCam Pro 9000 latest driversLogitech USB speakersWindows Vista on DELL Vostro 220
Thanks for the computer setup.Out of interest do you know what the other computer in the conference was using? Squeaking could be related to feedback or echo that is being "looped" through the external speakers and webcam microphone.It may be worthwhile checking that each computer has the "Voice Enhancements" ticked - these can be accessed by clicking "Audio Settings" at the bottom of the conference.http://www.nefsis.com/manual/cc-audio-settings.htmlAlso, checking the exact version of drivers (or checking for any updates) might help - as Logitech have recently released a new version (v2 - Build 13) of their software:http://www.logitech.com/en-us/435/6333?section=downloads&bit=&osid=13Otherwise, feel free to contact us (or post back) and we'll be happy to help as best we can.
