WinXP volume control that does not stick

[Chinarut Ruangchotvit]

I have a Compaq Presario 5410. I upgraded from Win98 to
WinXP Professional.

I open the Volume Control panel and able to move the
slider to increase the main volume. I am able to hear
sounds but the slider does not "stick" and falls back down
to the minimum level without touching it.

Audio would be fine provided I could keep the slider at
the level I want.

The ESS Technologies site mentions ES1869 has built-in
support for their drivers:

I have applied all critical and recommended updates to my
new OS. All software appears to work fine outside of
hearing audio.

If anyone can provide a pointer as to how to resolve my
issue, much appreciated!

Thanks,
