But I'm at a loss to what do after that. I don't have much experience/knowledge in compiling etc, but I still want to try out ogg. (I downloaded the source coz I have an OpenBSD machine, and there was no

I just committed what will eventually become the next version of libao. I've made some major changes: renamed stuff, redesigned the API, actually documented things. It *will* break any current libao applications (like ogg123). It is on its own branch, so it shouldn't affect the mainline libao code for a while. But beware: I want to land this branch before Vorbis 1.0 goes out. Please
