So programs are using another API.

There's a gstreamer plugin for sndio, it can play and record should
make most programs using gstreamer just work. I don't know how
gstreamer selects the default src/sink though.

Last point. During debug, you could run "sndiod -dd -a on -f rsnd/2"
in a terminal. This would hold the device open and show the clients on
stderr. Holding the device open will make the program that bypasses
sndio fail, which in turn may give hints on the program side.
