My precise issue was that input devices aren't shown in the Sound Settings dialog that's used in Unity – and that the input volume was set extremely low. Using pavucontrol and simply increasing the Microphone input volume was sufficient.
It's also worth noting that this does not affect the Sound Settings dialog that's used when you login with Gnome Classic. Only with Unity/Unity2D. In my case, I have a Radeon HD 5850, which has HDMI Audio. But this audio interface doesn't have an input. I suspect that might be relevant? I do have to select the correct audio interface first in Gnome Classic. That's not possible in Unity.
