I recently bought a microphone headset to use with MSN.  On my computer running windows XP it works fine - people can hear me and I can hear them.

On my computer with Vista though it doesn't work.  I can hear other people but they can't hear me.  The microphone works with the computer because I can record my voice onto it.  It just doesn't seem to work with MSN.  Is this a Vista issue?  I have gone through the audio setup on MSN and it's all configured correctly. 

Check the software box sounds like its not compatible with vista like you said.

it didn't come with any software, it's just a headset that you plug into the sockets.  i can record onto my vista computer with it, it just doesn't seem to worth with msn (although the headphone parts of it do).
