nvsoud problem

[BoB_Xygene]

The latest Nforce drivers for linux seems to be very cool so i have tryed to install them.
I run the installer and it builds the two modules without problem at the correct place.
I modify modules.conf and modprobe.conf to reflex the new names of the modules driver for the ethernet and the APU.
And when i reboot the nvnet module installs successfully without any error, but the nvsound module simply freezes the computer when modprobed.

To correct the problem i went to bios in search of a PNP option as said in documentation but i don't have one in my Abit NF7-S V2 latest bios(Nforce2-400Ultra). I have removed all specials actions i had in modprobe.conf for the precedent driver and it continues to freeze.
The acpi is loaded and working may it be the problem or have i to rebuild the kernel with special options?

Please if someone knows the solution to the freeze let me know it.

ok fighted a little and i can give theese infos in regard to my problem:
Kernel is a mandrake 2.6.3-15mdk non modified.
I load the nvsound module without freezing if i disable acpi via bios or via lilo option.
I get some sound but i have poor vidéo performance with 6106 that works very well normally and after some minutes of play the computer freezes.

When i dmesg i get theese messages that claims that module nvsound is problematic to kernel:

I will continue investigation but i think my competences will not be enought.

Try passing the kernel boot parameters 'acpi=off' and 'noapic' .

If you use Grub you need to edit the file grub.conf (/boot/grub/grub.conf on my system) and add the above to the line specifying the kernel.

I had similiar problem and it got corrected when i turned off acpi and apic.
Does anybody know how i can create the center channel and LFE for stereo files under linux. The win driver provides and option to create these channels artificially. I could not find any such option under linux. Or is there any plugin for xine/ xmms/ mplayer/ etc that may create the center channel artificially from stereo files?
