This sounds exactly like you are recording the outgoing audio. The windows
drivers for some sound cards does that by default. Go to the mixer, select
the recording options and enable all controls so they are not hidden. 
Check which sources are used for recording. 

E.g. all the Dell desktops we purchased this year have audio drivers that 
by default record the outgoing audio.
