I have an issue that I've never had before.
When I typically configure my sound devices, I'm able to disable microphone playback. This is no longer the case.

At the moment I'm using Windows Vista.
There are no available options in the Volume Mixer or Device Properties. (They have always been available with other devices)
I don't want to hear everything the mic pics up (like static and movement feedback).

Is there some kind of custom driver or hack for this?

EDIT: Device is "Logitech ClearChat PC Wireless(tm)"
EDIT2: Restarting the PC had no success.
Additionally, drivers are up to date.

Post I made on the manufacturer's web page: http://forums.logitech.com/t5/Headphones-Headsets-Microphones/ClearChat-PC-Wireless-Can-t-disable-microphone-playback/td-p/594434

Vista and 7 have drivers for almost any hardware, so manufacturers often don't bother releasing them on their own or making powerful guis. What we end up with is a castrated interface.

I had a similar problem I could fix by downloading a generic driver for my soundchip from the realtek site. So maybe you should try the same as I think a missing setting is not Logitechs fault.
