I've started working on porting pulseaudio (a feature-rich esound
replacement) to NetBSD again.
While I could build it simply by having ioctls with
SNDCTL_DSP_GETODELAY (output latency) return EINVAL, pulseaudio won't
perform nearly as well in many cases if it doesn't have this
information.

I'm wondering if there's anything precluding the implementation of
this and/or if anyone's looked into this before.

Thanks,
