You needn't even do a full kernel compile. Just compile the modules.
Just go to the kernel source directory (make sure your kernel sources /usr/src/linux
points to the correct kernel source path:
(open a terminal window if you're in X)
( as root )
( Look around this menu-based config tool and find your sound card driver here and mark it <M> to signify it as a module )
( Save and exit )
(wait for modules to compile)
Then check with modprobe
to see if you can load the emu10k1
Hope this helps. Regards.
