Are you involved at all with the Bytecode Alliance or the decisions around the WASI proposals/standards? It feels like your take on these things would be super valuable given all the work you've done. They're a very open minded group.
Also, with the solid foundation and simple API footprint you've built for APIs like sokol_audio, would be interesting to see if they could be expressed in WIT and used as a basis for something like a wasi-audio.
+1 for Audio and lots of other APIs necessary to make WASI more like a true OS. With Preview 2 / Component model, hoping the pace of contributions rapidly increases.
