There's probably some template trickery you could do, but I don't much 
see the point since dynload is a bad idea anyway. It just causes some 
codecs to silently not work at run-time if the library doesn't load for 
some reason.

That's rather interesting. mpg123 is the one codec that gave me quite a 
bit of trouble to work with dynload, since I couldn't use a number of 
its normal functions. What problems do you have without dynload?

FWIW, it now also uses libvorbisfile and libFLAC directly, without the 
need for libsndfile. It also has its own wave file handler for formats 
that OpenAL can take directly, and which will read smpl chunks for loop 
points to automatically set them on buffers using AL_SOFT_loop_points. I 
haven't yet looked into how vorbis and flac files specify loop points, 
if they do at all, so only wave files have automatic support for loop 
points... though they can still be specified manually if the extension 
is supported.
