--- Comment #4 from Tanu Kaskinen <tanuk at iki.fi> ---
module-loopback doesn't ignore the option, there's a different explanation for
the observations. If changing the default fragment size has some effect, then
it means that the sink (and probably source too if they're the same card) are
not using timer-based scheduling, and hence don't support dynamic latency.
Without dynamic latency, module-loopback can't control the overall latency. Or
more specifically, it can't make the latency smaller than what the sink and
source allow; it can be considered a bug that latency_msec=2000 doesn't make
the latency higher, because that should be possible to do.
