Lost Windows XP sounds after Logitech web cam software upg..

Archived from groups: microsoft.public.windowsxp.configuration_manage (More info?)

I recently purchased a Logitech Web Cam Pro 4000 with built in microphone,
installed the included version 8 software, camera and microphone work fine
for webcamming over RoadRunner cable connection. First problem was that
Yahoo Messenger wouldn't load from the Logitech window, no problem though
because I could start it up separately. So I went to the Logitech web site
to see if there was an upgrade, downloaded 8.4.1 and installed it. Fixed the
YahooMessenger startup problem but now the sounds that should play when
Windows XP Pro starts-up and shuts-down don't play. Checked the Sound
settings in Control Panel and they are still at Windows Default and play when
I click the button. I've uninstalled the upgrade software v8.4.1 and
reinstalled the original v8 but that didn't fix the "no sounds problem". I
can't figure this out. Please help. Thanks, Mike
