I had a Live! and had *that* problem. Eventually upgraded drivers fixed it.
I then upgraded to an Audigy and didn't have *that* problem. Then I
upgraded from Win98SE to XP Pro and *that* problem magically returned, even
though no hardware changes were implemented.
I tried applying the drivers from my Audigy CD again (which only had up to
Win2000, but I assumed, wrongly, that they would be the same as the XP
drivers) and the problems got worse. I downloaded newer drivers and then
got blue screens and the original way back when problem of the volume
resetting to full after every re-boot returned.
Tried moving to different slots, even though I remembered that did nothing
when I first got my Live!...still did nothing.
To make a long and frustrating story short, it is a driver problem. If you
have an OEM version of the card, then the drivers are not available online.
If not, just get the latest drivers and it should solve any problems. My
solution was to get my vendor to burn me a copy of the current OEM driver
disk that comes with the card, because it contains XP drivers. Solved both
*that* problem and the volume resetting immediately.
