Very frustrating problem on m Dell D820 laptop:
The volume will occaisionally - sometimes frequently - drop to zero while playing music or a web-based video.
It does not seem to be tied into a particular application or plug-in, such as Windows Media Player, or Flash, etc.
The laptop has volume and mute buttons above the keyboard. Pressing any of these (vol up, vol down, mute) brings up a slide-bar volume graphic in the lower right of the screen.
(As an aside, For as long as I've owned the laptop, this graphic has popped up when certain keys on the keyboard are pressed, but with no rhyme or reason to it. Just happens occaisionally when typing.)
In the last couple of months, this volume problem has started - every 1 to 5 minutes or so, the volume just drops to zero on the main volume control. The only way to prevent it is to sit with my finger pressing on the volume up button.
Now it seems to be happening every few seconds. Then it will just stop.
Where would I start tracking down this problem?
I've updated all of my drivers and Bios to latest versions, etc.
