So the source of the loopback is the monitor source of the chromecast sink?

If the source of the loopback is the monitor source of the chromecast
sink, increasing the latency of the loopback module should increase the
latency of what is played to the alsa sink, not the chromecast sink.

It's a known problem that something is wrong in module-loopback related
to the latency_msec paramter:

The loopback patches that Georg Chini submitted recently probably fix
the latency_msec parameter behaviour.
