Ok, here are the updated instructions.

When you compile Alsa, the first step is normally to run './configure'.
In Ubuntu 10.10, you simply run './configure --with-oss=no' and that's it.
Of course, you run then 'make' and finally 'sudo make install', as usual.

I highly recommend to clean up the existing Alsa kernel modules from /lib/modules/.../sound/*
If you still get issues with unknown symbols, it is most probably related to left-over Alsa kernel modules (for example, soundcore.ko was left for some reason).

Still no sound and the module fails to load. I used the orginal snapshot that you had me download when we first started. I have atatched the process I used to compile, clean and install.

Verify destination

find /lib/modules/2.6.35-23-generic/kernel/sound -name "*.ko" -print

To remove them

sudo find /lib/modules/2.6.35-23-generic/kernel/sound -name "*.ko" -exec rm {} \;

Configure Statement

./configure --with-oss=no

make

sudo make install

Verify the files are back

find /lib/modules/2.6.35-23-generic/kernel/sound -name "*.ko" -print

Edit alsa-base.conf

sudo vi /etc/modprobe.d/alsa-base.conf

make sure that any snd-hda-intel is commented out.

reboot

No sound was the result. Below is from me checking the dmesg and trying a manual load.

I tried this configure line and still got the same results

./configure --with-oss=no --with-pcm-oss-plugins=no --with-debug=verbose
