I wouldn't be concerned so much about latency.

libcanberra supports different backends, as does PulseAudio.

I added support for pluggable backends precisely to avoid discussions
like this one: if someone wants to use libcanberra on his exotic OS,
he's welcome to do so, all he needs to do is write a backend. In the
ALSA driver he has a good template.
