How to setup GNOME esd with OSS drivers?

Hi,

My motherboard, Gigabyte GA-K8NF, has nvidia onboard sound. Without the 
nvidia drivers I have a terrible noise. After I installed the nvidia 
drivers, the noise disappeared and I can play music in xmms. 
Unfortunately, the system sounds disappeared too:-(.

After playing with it for a while, it seems to me that the problem is 
that esd needs to be setup to use (Open Sound System) OSS, because the 
nvidia driver is not an alsa driver. After I installed the driver, I had 
to (according to the manual) replace "alias snd-card-0 snd-intel8x0" 
with "alias snd-card-0 nvidia" in /etc/modprobe.d/sound. With the new 
setting, the scripts /etc/init.d/rc3.d/K10alsasound and 
/etc/init.d/rc3.d/S12alsasound fail to work and esd does not want to 
start even from the command line.

How to make esd work with an OSS driver?

Thanks in advance!
