Sound input on Fedora 15

Sound output through my motherboard's Intel HDA ACL888 works OK.
Sound input does not work.

Alsa lists the ACL888 as well as a video capture card.
Pulseaudio (pacmd list-sources) shows the card and says that it only has
internal audio monitor, not hardware input.

Any suggestions on how to fix this?
