Unfragile

The request names alsa-lib, which is not among the candidate products, and none of the listed products' sources describe it. The closest fit among the candidates is PortAudio, whose page names ALSA among the Unix audio backends it works with, and libsoundio, a cross-platform audio I/O abstraction. The request does not state a platform or use case, so it is unclear whether a replacement or an alternative to alsa-lib is wanted.

A question back: Do you want an alternative to alsa-lib for direct ALSA device access on Linux, or a higher-level audio library? Please name your target platform and language.
