Yes, there's a reason that I'm using PulseAudio's loopback module instead of
the ALSA monitor, directly. That doesn't have anything to do with this bug,
though.

Since I last commented, I was able to reduce the 'Sink Latency' (and the
module-loopback 'buffer latency') dramatically by correcting my PulseAudio
default fragment size from the default 25 down to a more suitable 3.

Although the 'Buffer Latency' value is no longer ~200ms, which defeats my
theory that module-loopback always uses the recorded default value of 200ms,
the latencies are still exactly the same regardless of whether I supply
latency_msec=1 or latency_msec=2000. I'm not sure of exactly how
module-loopback settles on its latency, but it still appears that the
latency_msec option is ignored, as far as I can tell.
