I think you guys might have hit on something regarding plasma TV's. I was having recognition difficulties as well with the senor both above and below my 65" LG plasma. I never even noticed the buzzing until you mentioned it, but the Kinect microphones seem to be SUPER sensitive. Did some testing with the TV off and just hooking up a small LCD monitor instead to test and recognition was significantly better. Tried to make everything as quite as possible, so I could listen for other noise sources. My STB/DVR hard drive makes a constant racket, but turning it off and on didn't seem to make much difference, so I think it's far enough away. One think I picked up on were the neon lights in my kitchen had a similar buzz as the TV and turning them off seem to help some too, which I found surprising considering how far away they are (25' ish). Hence my comment about Kinect mic sensitivity, with everything quite other than the stereo blasting away game audio, I could almost whisper and it would still pick me up.
It really is amazing when it works and incredibly frustrating when it doesn't. Now to come up with a plan which doesn't involve a new TV. Best option for me would be to tuck the sensor into one of a pair of stereo racks I have bracketing my TV, in which things are much quieter. Does anyone know what sort of issues you can run into with the sensor not centered with the TV?
