-However, the server side links to the GPL-only library 'libsamplerate' which
-practically downgrades the license of the server part to GPL (see file GPL for
-details), exercising section 3 of the LGPL.
-
-Hence you should treat the client library ('libpulse') of PulseAudio as being
-LGPL licensed and the server part ('libpulsecore') as being GPL licensed. Since
-the PulseAudio daemon and the modules link to 'libpulsecore' they are of course
-also GPL licensed.
+However, the server side has optional GPL dependencies. These include the
+libsamplerate and gdbm (core libraries), LIRC (lirc module), FFTW (equalizer
+module) and bluez (bluetooth proximity helper program) libraries, although
+others may also be included in the future. If PulseAudio is compiled with these
+optional components, this effectively downgrades the license of the server part
+to GPL (see the file GPL for details), exercising section 3 of the LGPL. In
+such circumstances, you should treat the client library (libpulse) of PulseAudio
+as being LGPL licensed and the server part (libpulsecore) as being GPL licensed.
+Since the PulseAudio daemon, tests, various utilities/helpers and the modules
+link to libpulsecore and/or the afore mentioned optional GPL dependencies they
+are of course also GPL licensed also in this scenario.
