Your problem is that you still have the intel8x0 module loaded.
Did you really do everything in my howto? Looks like you missed step 2, or maybe you did not reboot?

Yes I did both and just checked the two files edited on step 2 and they seem allright. I rebooted many times already. Any ideas?

Weird... Could you show me the contents of your /etc/modprobe.d/blacklist?

# This file lists those modules which we don't want to be loaded by
# alias expansion, usually so some other driver will be loaded for the
# device instead.

# evbug is a debug tool that should be loaded explicitly
blacklist evbug

# these drivers are very simple, the HID drivers are usually preferred
blacklist usbmouse
blacklist usbkbd

# replaced by e100
blacklist eepro100

# replaced by tulip
blacklist de4x5

# causes no end of confusion by creating unexpected network interfaces
blacklist eth1394

# snd_intel8x0m can interfere with snd_intel8x0, doesn't seem to support much
# hardware on its own (Ubuntu bug #2011, #6810)
blacklist snd_intel8x0m

# causes failure to suspend on HP compaq nc6000 (Ubuntu: #10306)
blacklist i2c_i801

blacklist snd_intel8x0


Also when I type sudo gedit /etc/modprobe.d/blacklist I get this on the terminal before getting gedit window:

The file looks exactly like mine, so apparently something else is causing your problem. I'm not sure how to help you figure it out, I'm definetly not an expert.

I think the alsa errors are caused by the intel8x0 module (nvsound uses oss instead of alsa).

Fixed it. I had a set Nvidia nforce 2 sound driver on my Sounds section of Ubuntu. I put Autodetect on everything and now it works flawlessly. Will this give true 5.1 sound on movies or will it just throw out same sound through all speakers?

Thanks a bunch. Great guide.

Cool.
I get true 5.1 sound if the audio track of the video is 5.1.

[PRGUY85]

I am using a 5.1 DVD and getting same sound from all speakers. I dont have a digital output to my speakers though since I dont have an external receiver or anything.

I have DFI NFII U400SG-AGF motherboard

http://us.dfi.com.tw/Product/product...B=3244&SITE=US

does this have soundstorm support?
manual says "South bridge: nForce2 MCP GIG"
but not MCP-t

Sorry, but I think you only have the AC'97 codec. According to DFI's description:

Audio
AC’97 CODEC
S/PDIF-in/out interface
6-channel audio output
