Hi, in my case, I think it was simply a missing package dependency. Installing the libcanberra-pulse package fixed it for me.
gnome-control should probably add libcanberra-pulse to a proper dependency rather than just recommends since it's likely common that people would want to test speakers and the test silently failing (e.g. control-centre doesn't even warn its missing the libs it needs) makes a user (me for example) get lost (i.e. inspecting ALSA, etc) when the silent test failure misleads.
