Query: No sound.

I bought this item because of good reviews. However, the one I got had no sound when you plugged the microphone which should be plug and play. I returned and got another one but I had the same problem. I called the manufacturer and it was verified there was technical issues. I do not know if it is just a fluke but both of items I got were defective. Needless to say I do not have one now.
