xmms volume knob - seemingly all or nothing

[Aaron Peterson]

I have not set up 4.x on this hardware, in fact one reason for using 5.2
was because it is relatively new hardware, and the onboard NIC wasn't
supported under 4.x it seemed.

Anyway, the volume control in XMMS seems to do nothing at all from about
the 5% mark to the 100% mark, music plays at the same volume no matter
where the slider is in this range.  between 0% and 5%, the music fades
from silent to full volume.  I have never experienced this phenomenon, and
am wondering if I can adjust some non-xmms mixer setting to get the
expected behavior, or possibly adjust xmms somehow.  I don't even know
where to start really.
