Sorry for a late reply, I haven't had time to read bugmail for a while.

Are you loading module-loopback manually, or is it getting loaded
automatically? If you're loading it manually, you can try using the
latency_msec parameter of module-loopback.

If module-loopback is getting loaded automatically, then it's not possible to
control module-loopback's latency, because module-bluetooth-policy (which
handles loading module-loopback) loads module-looback always with the default
latency. You could modify system.pa to not load module-bluetooth-policy, and
then load module-loopback manually, but manual loading may of course not be
practical, if you have to do it every time you connect a bluetooth device...

Another possibility might be to force the alsa sink latency to be higher. To
try this, add tsched=no to module-udev-detect's parameters, and increase
default-fragments and/or default-fragment-size-msec in daemon.conf (those
parameters only have effect when tsched is disabled).
