can't create /dev/dsp

I have the following motherboard

Manufacturer: FIC
Form Factor: Micro ATX
CPU Socket/Slot Type: Socket A (472 pin)
Chipset: nForce 2
RAM Type: (Various) DDR PC2700 DIMM
Number of RAM Slots: 2
Total RAM Capacity: 2048 MB
RAM Stick Size Limit: 1024 MB
BIOS/CMOS: Phoenix/Award
Front Side Bus Speed: 200/266/333 MHz
ISA Slots: 0
PCI Slots: 3 (Version 2.3)
AGP Slots: 1
Onboard Video: nVidia GeForce 4 MX (Integrated) AGP
Onboard Audio: RealTek ALC650 (AC 97 2.2)
Battery: CR2032

I am running mandrake 10

everything worked right out of the box except for the sound. And it is really frustrating. I recently migrated from FC1 because I thought that a 2.6.x kernel might solve my sound problems... but it didn't.

Essentially it looks like mandrake has installed all the correct alsa drivers, modules, and that everything has been detected correctly, but I get a message that the /dev/dsp can't be found, and in fact it does not exist. I tried making the device myself, but that didn't do anything.

Looking at the logs from when my system starts up i get a strange message about IRQ 0... can't remember exactly what it said (i'm not at my computer now) I'll post that later. Meanwhile any suggestions would be really appreciated.

I'll try that. I tried it under fedora, but it didn't work. Perhaps it will be different now that i'm using mandrake and my kernel is 2.6.x instead of 2.4

Try compiling ALSA yourself, download the alsa-driver, alsa-lib, and alsa-oss packages from here:
Compile them in this order:
After you install the alsa-driver, run ./snddevices.
