Then the problem is that Pulseaudio isn't getting anything from the
sound card's microphone input. The sound card seems to have multiple
ports. What if you try to select some other port on the Input Devices
tab?

If changing the port doesn't help, then the next thing to try is to
desperately flip random mixer switches using "alsamixer -c0". If that
helps, please report back what elements needed changing (with luck we
might be able to incorporate that information into the default
configuration so that in the future your sound card would be supported
better out-of-the-box).
