Why audio latency in loopback is divided by 3?

[marcin@xxxxxxxxxx (marcin@xxxxxxxxxx)]

Hi,

I found interesting piece of code in module-loopback:

int pa__init(pa_module *m) {
(...)
    pa_sink_input_set_requested_latency(u->sink_input, u->latency/3);
(...)
}

I understand it sets the desired latency, but what is the reason for
this division by three? Why 3 not 2, 5, 88 or 3213?

(now I understand why default latency for loopback is 200 ms and I had
always noticed strange 66 ms in pacmd).
