I've searched through the posts and all over the internet and find no one has got the rear speakers working on NVIDIA chipsets. Not one for giving in, I located this link
http://www.asus.com/support/faq/qanda.aspx?KB_ID=85096
I no that everyone has been focused on the NVIDIA nforce2 drivers and alsa in combination for a fix. I am a newbie, but am I on to something here? I hope one of the Gurus or MasterCs
( HeHe a little play on words ) get a look at this in hopes of coming up with a fix.

You could be, however, anyone who runs an "lspci" on your board would quickly see that is indeed the case, also, when we were 'monkeying' around with the audio, it came up several times that it was the RealTek chipset, not the SoundStorm, so I don't know how up and coming that info would be

Either way, let's move this to the Hardware section where it might get a bit more attention from those who know. Moving to Linux - Hardware.

Cool

I am trying to get my 6 - ch sound working on my Asus A7N8X Deluxe motherboard. It has Realtek ALC650 onboard. When I try to unzip in step 1 I get
[root@localhost dad]# tar xfvj alcsound.tar.bz2
tar (child): alcsound.tar.bz2: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error exit delayed from previous errors
[root@localhost dad]#
Would someone please walk me through this?
I downloaded the following site
http://www.abxzone.com/forums/showthread/t-53577.html
These are the instructions:
Step 1. unzip source code
tar xfvj alcsound.tar.bz2

Step 2. Turn on sound support (soundcore module, default turn on)

Step 3. Complied source code
a. ./configure
b. make
c. make install
d. ./snddevices

Step 4. Edit your /etc/modules.conf or conf.modules depending on the
distribution
(Please refer to the attached modules.conf)

Step 5. reboot your machine

Note: 1. The most detail information, can refer the
alsa-kernel/Documenttation/ALSA-Configuration.txt
in the alcsound.tar.bz2.
2. Kernel Version must be 2.2.14 or later.
3. All mixer channels are muted by default. You must use a native
or OSS mixer program to unmute appropriate channels.
4. If can not compile the source code, try to rename the
/usr/src/linux-2.x -> /usr/src/linux.
5. The driver added to support the SPDIF functoin.
6. Suggest use alsamixer to control mixer function. you can find it in
the alsa-utils-0.9.4 (www.alsa-project.org).
