I do not know if they have fixed the old problem in the make file. In 14.0
the script cleans out all of the snd-*.o files from
/lib/modules/<version>/kernel but not the .k0 files which are now more
usual in kernel module trees. This means that there is a danger thatold
module files are left which completely messes up module loading. 
Check to make sure that there are no snd-*.ko files

find /lib/modules/<version>/kernel -name 'snd-*.ko'
(alsa tends to use the .o form not the .ko)

That says that alsa was never loaded.
