Volume Too Low, Different Chipset on Alsa and OSS Mixer

I try to configure a generic sound card on my friend PC with Mandriva 2008.0.
The dmesg report Ensoniq Ens-1371 chipset.
But Alsamixer report CS-4297.
On Gnome-volume-control, there are 2 devices:
Ensoniq audiopci and Crystal CS-4297.

Everything works, except the sound volueme is too low. The faint sound can only be heard by using a headphone.

There is a master hardware volume control set using Windows program, but I cannot find similar program for Linux.

I had tested alsamixer, kmix, aumix, gnome-volume-control to increase the volume, but all failed to increase the sound.

How to solve this "low volume" problem?
Is this problem related to dual chipset design?

Is there any special master hardware volume control utility for Ensoniq board?

Relevant output of lspci -vvv

Check lsmod, modules.conf,

Have you set the module options correctly?

Relevant or timely? don't know, but I did just find a great solution for extreeeemely faint sound.
Open terminal, type su root, then at prompt, password.
type alsamixer - up pops control panel, use arrows to go across the columns, and up arrow to increase the various volume settings.
then type alsactl store to store the settings. all done.

(If like me, you've already messed about with settings in the System/Preferences/Sound place, then jst go thru each one and hit test button, and somewhere you'll get a piercing volume signal that wakes the household as I did.)
I haven't learnt to express instructions as elegantly as more experienced users, so in case its ambiguous, here's where I got it.
