No problem, I'll try to elaborate a bit :) As you propably know, ALSA is the combination of API and drivers that is commonly used for sound in linux. The kernel sources include ALSA, but since it is developed separately, there also is the possibility of installing a version of ALSA different from the in-kernel version, which is mostly done to get a newer version of ALSA that includes new support for chipsets (seems to be your case).
When compiling, the em28xx driver includes the ALSA header files that
come with the kernel (at least I suppose so), which also encodes the
version of ALSA compiled against into the generated kernel module. If
you are using a version of ALSA that differs signisficantly from the
in-kernel version, the kernel will detect the version mismatch and
complain, which is what your error message look like to me.
Could you post what kernel version you are using, so that we can check
what the in-kernel ALSA version is (most likely 1.0.14). If this indeed
is a version mismatch, then we can try to patch the dvb-experimental
tree to include the correct kernel headers.
