This is bad. Recommends is defined as things that are usually, but not
always, installed together. Not installing them may leave your system
not working as intended.

If some Recommends is unwarranted, please file bugs against the
respective packages.

The solution is that pavucontrol Recommends pulseaudio. Pavucontrol is
more than willing to work with a remote server if so instructed, so a
hard dependency is not required or necessary.

Wheezy will not receive the fix.
Currently Jessie is in freeze, and should be released soon (for some
values of soon).
