Routing the laptop mic to the hf device and the hf device input to the
laptop speakers should happen automatically. It's done by module-
bluetooth-policy (which is included in the default configuration),
which loads module-loopback instances. The loopbacks connect the
bluetooth source to the default sink and the bluetooth sink to the
default source. As long as the default sink and source are set
appropriately, this should just work.
You can check the current default sink and source with "pactl info",
and you can set them with "pactl set-default-sink" and "pactl set-
default-source" (see "man pactl"). Graphical audio configuration tools
can usually also be used to set the default devices.
If module-bluetooth-policy doesn't seem to be doing its job, please
attach the output of "pactl list".
