Ubuntu Multimedia :: Gnome Sounds Fine, Xfce Is Too Quiet?

I originally installed Ubuntu 10.10 in my computer, but as it is an older machine, it was too heavy for it. Threfore, I installed the xubuntu-desktop package available at the Synaptics package manager. From then on, my system began behaving pretty much like a pure Xubuntu 10.10, or at least as I think it should be. I still have the option of selecting between a Xubuntu and an Ubuntu session at start up.

That said, there is a little thing that is annoying me. While the sound in Ubuntu sessions are just fine, it is too quiet in Xubuntu ones. Let me elaborate: I think that the maximum volume is the same, but while Ubuntu's volume curve is a straight born from an arithmetic progression one, Xubuntu's sounds like a curve born from a geometric progression, that is, it is too quiet at lower levels, reaching its maximum very abruptly. I control sound using volume keys, and the computer reaches maximum volume in 20 pressess. While in a quiet place I can reach a nice, audible volume at 3 pressess in Ubuntu, in Xubuntu I only start hearing something at the 10th or 11th press.Is there any way to make Xubuntu's volume control behave like Ubuntu's?
