shairport-sync gets latency information from PulseAudio, and that should be
sufficient to keep the outputs in sync. If that doesn't happen, I believe it's
either a bug in shairport-sync, or the latency information from PulseAudio is
wrong, in which case it's of course PulseAudio's fault (or the alsa driver's,
but if it works with plain alsa, that seems unlikely).</pre>
