I think I'm having slightly similar problems. (See my earlier post a few
days ago).
As I understand it, the C header files that were used to compile the
current kernel are at /usr/include/linux/ and these are needed to
compile the ALSA module (so it knows what "hooks" are in the kernel). If
you compile some other kernels their header files will be slightly
different, and will go in /usr/include/linux-2.4.13/ etc. (one for each
version)

For some reason I'm not sure of you can't just use the running kernel's
headers, you have to have the entire kernel source code in
/usr/src/linux-2.4.13/ or whatever. (The Kernel Compiling HOWTO  and the
kernel README has stuff on this). Perhaps the standard RH7.2 kernel
doesn't have support for the ALSA module or something?

I might be wrong here but this is my setup and ALSA compiles OK for me
(RH 7.1) for kernels <= 2.4.13
I think I was using the same ALSA version, I think there is also a 0.9
version which is more experimental and might be needed for later kernels
perhaps?

Please someone tell me if I'm talking nonsense here.
