Vista - Skype brings volume down

When I commence a skype call volume starts going down until muted. I have to
turn it on manually and then it works. Until the next call.
The problem started after I installed drivers for Microsoft Live Chat USB
Headset.
After these drivers removal and skype reinstallaion the problem still
persists.

Any suggestion is very much appriciated

In the Options for the USB headset, is there anything like a setting to
automatically adjust the mic level? If so, disable it.

I have the same problem as Vladimir.

Skype automatically switches the recorder and playback from my settings to
Sigmatel and mutes the sound.

This happens despite:

a) Unchecking - Let Skype adjust my audio settings
b) Choosing Windows Default Device in microphone, speakers and ringing.

I note in another forum... (MSDN Forums » Audio and Video Development »
Media Foundation Development » Programatically setting the default playback
device (and recording device)) ..... that setting the default playback and
recording device is not allowed in Vista. Then how come Skype is able to do
it?

I am surprised that this has not been resolved as I have the same problem.
I have Vista Ultimate x64, with logitech mic and external speakers. When making a skype call the volume mixer in the tray shows all the volumes crashing to zero. people can hear me but I can't hear them. Physically returning the levels corrects this until the next call. After setting up all the audio equipment correctly I feel that it is a realtek issue but I can't be certain.
Someone out there must have an answer! I have been tearing my hair out and wasting a lot of time trying to sort this out!
