I'm getting the following warnings when I start pulseeffects and all the effects are grayed out:

Before last update (groovy) everything was working fine.
Looking at the apt logs it seems that yesterday the package libgstreamer- plugins- bad1.0- 0 has been updated from 1.16.2-2.3ubuntu1 to 1.16.2-2.3ubuntu2. I don't see how, but maybe it's related to this problem... I'll investigate more.
