The LADSPA equalizer is not very reliable, so I'm glad to get a useful bug to report.

It seems like the profiles in "System Settings" aren't correctly related to the ones that are actually in use, and I'm not sure whether this is because of the plug-in or not. When I started playing a song in Amarok, the profile *actually* in use was "Digital Stereo Output + Analog Stereo Input," even though "System Settings" indicated it was "Analog Stereo Duplex." When I changed the setting to "Off," the profile in use did not change--PulseAudio crashed, then restarted correctly with the LADSPA plug-in and digital stereo output profile.

How to reproduce
-----
1.) Play a song in Amarok.
2.) Enabled LADSPA Equalizer plug-in with "PulseAudio Equalizer" application.
3.) Close PulseAudio Equalizer (plug-in still active).
4.) Open KDE System Settings, go to Multimedia, then Phonon, then Speaker Setup.
5.) Changed profile from "Analog Stereo Duplex" to "Off."
6.) PulseAudio crashed, then restarted, with Amarok playing the next song in the playlist.
