Can't get the sound server up [drivers version 1.0-0292]

[ibm2080]

Hi,

I am running Debian SID/unstable with kernel 2.6.9 and KDE 3.3. I have an Asus K8N-E Deluxe mobo with nForce3 250Gb. I installed the nVidia drivers just fine, then used modconf to load the nvnet and nvsound modules. The nvnet one works just great (even after reboot). But I can't get my sound server up. aRts fails to start. When run from the command line, here is the output:
>>>Start of paste<<<

This might be a sound hardware/driver specific problem (see aRts FAQ)

I tried to run it as root, but there are a lot more things printed to the screen, mainly info. However, the error is still the same. I couldn't find anything in the aRts FAQs about this. I looked in dmesg and the Nvsound module is loaded just fine. I made sure that the OSS modules are built into the kernel as I build my own custom kernels.
Does anyone know what is going on here?

Thx,
