Hello Again..I have used 3 sets of HP I know work on other devices.So that's out. The driver that loads automatically is a MS HD driver that shipped with the box. This works but no HP. HP worked with that before. The GW site has a updated IDT(SimgaTel) HD driver which also works but no HP. This driver loads a line item to services which allows for the monitoring of the Jacks.This indicates that "some other device" is plugged into the jack for both the mic and HP. The HP worked with this driver until it suddenly stopped. That's when I did a restore to no avail. I'm going to download the IDT driver again using the zip file, not the .exe method and go from there. Thanks for sticking with me on this.I'll post back.Like you I just cannot believe this is hardware related.
