Heya folks, did a bit of searching on the forums, and couldn't find any clear answer to this problem, so I figured I might post and see if any of the more expert people can figure this out. I've recently started using Skype a lot more than I used to, and so I decided to buy a proper headset. Got a nice little Plantronics one, seems like a good unit. So I plug it in, one plug into the headphone jack, the other into the mic jack. I can hear without a problem, but Windows is still using the internal microphone. Is this just a matter of fiddling with the settings, and if so, which ones? Or is this a hardware compatibility issue, and if so, what would work hardware wise? MacBook 13" Late '08 running Windows XP SP3.
