Hey, I recently bought a new Razer Piranha Headphone/mic set. It boasts nice voice quality, but for unknown reasons the mic will just cut out for long periods of time. My system still detects the mic/headphones plugged in, but nothing can record the voice. Xfire won't, and Windows Vista sound recorder won't detect any noise.

Well, what could be the problem? My system is an Emachines T5246 standard (only a Nvidia Geforce 8800 GT OC by PNY has been added). Everything else the same. In the device manager, it shows "Realtek HD audio", and it says its fully updated. I'm new to Vista, and quite sure if I haven't done something quite right. Thank you for any help you offer.
