Línea de trabajo

Start with src/lib.rs in the wasm example, especially the code around lines 46–76 shown in the compiler output, and compare its build_output_stream call and sample type bounds with the CPAL 0.15 API. Check whether the reported errors still reproduce with npm run start; done means the example compiles and starts without those errors.

the first function requires another argument (a duration it seems) ,
and then there is an issue perhaps with context regarding Self...
...very interested in diving into your library but yes...thx!
