Playback-only (default) works, record-only crashes:
$ pulseaudio --dameonize=false -n --load='module-sndio playback=false
record=true'

and move the offending debug log into `if (mode & PLAYBACK) {' which sets up
u->ink so it doesn't get accessed in record-only mode.
Then pulseaudio starts, burns too many CPU cycles and I haven't figured out
yet how to record from or otherwise verify that PulseAudio actually gets a
mic from sndio, but that's better than crashing...
Feedback? OK?
