Kent,
I am a registered user. I have the same problem and I believe it is possible that most everyone else does as well.
I have a volume control on my wireless keyboard and the volume indicator on the screen dutifully travels up and done with no effect on the volume whatsoever.
I have to click and drag the control. I used to have to run the Mixer application to change the volume.
Before I start SoundTap everything works fine. I can deal with this because this product does a bang up job of recording. I think it is the best solution available bar none.
My friends think I'm a genius for finding this product. (My wife could care less )
On the other hand, if NCH could fix the volume control irritation it would be GREAT.
