Xonar DX & Sennheiser PC 350 Not Cooperating

I've been having intermittent luck getting the mic to work on my Sennheiser PC350. It worked at one time or another with DragonNaturally, Skype, and gmails phone service. Now it doesn't seem to want to work at all. Even though, as you can see in the attached image, Windows shows that the 'device' is working. Also attached, but not shown, is my Logitech Quick Cam Pro 9000. This has a mic built in and it functions properly.

Any ideas where I should look to solve this mystery?

I'm not certain that it will fix it, but select the Properties button on the Sound Properties and make sure that "Use this Device" is selected in the dropdown window. Then on the Listen tab, make sure that "Listen to this device" is not checked. On the Custom tab, make sure that "Microphone Boost" is selected. On the Levels tab, make sure that the volume slider is at 100% and that the mike is not muted. Then go to the Asus Audio Center and try enabling AEC and check that the volume is 100% there also. If none of these help, then I would suspect that the mike has a problem, and may have to go RMA, if under warranty.

Except for the AEC, everything is in order. I'd hate to think it's a repair issue, they're not that old and I'm very gentle in handling them. I guess I''ll try them on another computer.
