since new about 4 months ago, the master volume goes down by itself to cero!!, here what I have done
-reinstall Vista, update realtek drivers, changue keyboard and mouse, update bios, remove reinstall drivers in safe mode, disable the built in sound and install a sound blaster audigy pci card, play thru many settings, install windows XP in second partition and install all proper drivers, so I have this machine w/dual boot.
And the problem still there!! in Vista or XP is the samething, sometimes works for a day sometimes for a minute, it happens w/any player, even when nothing is playin, of course I have checked for virus, spyware, etc.(Hp tech support does not know anything about this machine, not new)
Please help!!

This sounds like a Good Old Software Conflict

by OH Smeg Moderator In reply to VOLUME GOES DOWN TO CERO ...

But just to be on the safe Side look in the Device Manager for any Conflicts that may be occurring and change the Resources from Auto to Manual if necessary.

In XP you get there by Opening the Start Menu, right Clicking on My Computer and then left clicking on Proprieties. When the next Window opens left click on the Hardware Tab and then Device Manager. when the next window opens expand the different headings and then right click on the Individual Items and select Proprieties from the Drop Down Menu. When the next Window opens left click on Resources and make the changes there.

Note not all of the devices have the ability to change the Resources so you need to look at them all and make any changes there as you go along.

Make one change at a time reboot and see if the problem persists. If it does go back in and make another change and restart the system again. Continue to do this till either the system is working properly or you have run out of devices to change.

If that doesn't work post back.

The other thing you can try is using the HP Supplied Recovery Disc and rebuild the system to As New and see if the problem persists with no additional software installed. If it does you really need to contact HP and get them to fix their own problem but if it doesn't start installing one piece of Software at a time till the machine is either fully loaded or the problem pops up. When the problem starts you need to remove the last piece of Software that you installed as that is the problem.

It's a good idea

by Jacky Howe In reply to VOLUME GOES DOWN TO CERO ...

to use the System Restore feature when installing new software. If you create a Restore Point you can Restore to it if something goes wrong.
