Check Control Panel - Mouse and Keyboard to see if anything is set to Volume Control such as a middle
wheel, side button, or a key is "Stuck". Does it do it in all programs? If not check those that do to see if
they have programmable "hotkey" or "mouse" activated volume controls.

There was an issue in XP where older drivers allowed that so Update your drivers (XP or Vista).

Right Click Speaker Icon - Playback Devices

Highlight Speakers - Properties (lower right same page) - Enhancements  Tab - Check Disable all Sound
Effects - Apply - OK

Control Panel - Device Manager - SOUNDS - look for HD Audio - Mine says RealTek High Definition Audio 
(that is an example and yours may have an entirely different name/maker).

Write down description make and model - double click on it - drivers tab - write down version. Now
Click UPdate Drivers which may not do anything as MS is far behind certifying drivers. Then RIGHT
CLICK on it and UNINSTALL - REBOOT - this will rebuild the driver stack.

1st go to system maker's site and look for latest driver Download - SAVE - go to right click on and
(This is your fallback.) REBOOT after each driver installation.

NOTE : Sound driver often rollback so check the version after installation and the reboot to
see if the version you installed is there, if not repeat - reboot until it is. It can take several
tries depending on how many rollbacks it does.

Then do same for Device Maker's site.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Show disable and disconnected devices. Highlight speaker and the on lower Right click Properties
check settings for Device Usage enabled and so on. Also do same for Configure on Lower Left of
that box.

In Control Panel you can also look for an Audio Manager along with the Sound Settings.

Please do the above first. If those do not help then something loading at startup may be the cause and
these can help you use a process of elimination to try to see if that is so.
