Follow up from #246726 (sndio in multimedia/mpv) and #211664 (added the sndio option to audio/openal-soft). It looks like enabling sndio by default on openal-soft might be tricky, because the package starts depending on sndio and that means that for all packages that depend on openal-soft (that's over 100 ports), sndio would be a transitive dependency. Maybe this could be considered similar to how wayland was enabled by default? I don't really know how that came to happen, but it certainly is making things easier for wayland adoption.
> sndio would be a transitive dependency. *shrug* audio/sndio does not have any dependencies itself and is fairly small so this is justifiable IMHO. The only downside in enabling it by default is that OpenAL will prefer the "sndio" driver over "oss", but I doubt many people would notice at all.
