Volume all the way down, still sound!

I have never had this problem before. When the volume is all the way down (off) there is still audio coming from my speakers (or headphones). The volume works fine going up and down, I just can't turn it any quieter or off without using mute.

This has just recently become a problem, and I have checked all the sliders and audio options etc and still can't find out what is causing it. I know it is not the hardware.

Ok I solved it. I don't know how, but some wrong drivers got installed for my onboard audio. Reinstalled the correct drivers and its working now.

volume won't turn down unless I mute it

Where did you go to change your drivers. Worked fine when I got computer a month ago. Now all of a sudden volume wont turn down Please help

First make sure to fiind and download the right drivers for your motherboard or soundcard. Then go to device manager (you can right click my computer and go to manage), and find your sound controller and go to properties, then uninstall it. Then install the correct version that you downloaded.
