I downloaded the latest alsa-driver tarball from http://www.alsa-project.org/snapshot/ (which was alsa-driver-1.0.23.96.gda8b0.991.gd36e7 at the time)
I ran:
./configure --with-kernel=/usr/src/linux-headers-$(uname -r) --with-isapnp=yes --with-cards=usb-audio,hda-intel --with-sequencer=yes
make
sudo make install
However, now aplay -l returns aplay: device_list:235: no soundcards found...
When I rebooted or tried to manually load the modules, I got the following error:
sudo modprobe snd-hda-intel
FATAL: Error inserting snd (/lib/modules/2.6.35.4-custom/kernel/sound/acore/snd.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Trying to load the usb-audio driver produces similar results...
I rebooted into the generic kernel and the audio works. Any help pointing out what I did wrong would be greatly appreciated.
And FYI, I did compile a custom kernel (used the .config from the base ubuntu kernel and upped the clock to 1000hz... that was the only change).
