I used to have my alsa drivers which are different to the OP, built in the 
kernel.  For years on end.  Then alsasound stop working - something like 5 
kernels back, can't recall exactly.  I had to build alsa separately as 
modules.  Haven't tried to go back to building them in the kernel again.

YMMV.
