Sorry, no binaries at the moment, if you want to try compiling from source:
http://www.simonoc.com/files/ad/quakespasm-0.92.2-admod-source.zip
run
make USE_SDL2=1 from the quakespasm/Quake subdirectory to build. You'll need dev packages for libsdl2, libmad, libvorbis installed from your distro's package manager.
