|My volume control does 3/4 up and 1/4 down. But not all the way up. Not all the way down. Found out from someone here what the answer is:|
If you have Magic Jack, that is the culprit. Go to your MagicJack console. Click MENU on the upper right hand corner of the window. Pick Volume Headset Control. Choose device "Telephone". On the bottom, drag the speaker button all the way to the left.Close the window.
That should make it work now.
Hope that helps.
