I have a Microsoft LifeChat LX3000 USB headset that I'm trying to use and I have a couple of problems with it. It's set as the default device for audio, but unless it's plugged in when the PC boots it has no sound, however if I use the control panel for audio and the attendant audio test both the mike and headset are active and the mike test shows recording, yet there is no sound on playback. If I boot with the headset plugged in I get sound, but now the control panel audio test function doesn't work at all. 2 questions, how do I get the mike function to work and how can I switch from the USB headset to the front panel miniconnector audio? I'm running XP home with SP3 and using the integrated sound chips.
