I found a related Ubuntu question (which I have attached to this bug) where the author suggested moving the card to another slot. I tried this, and the card was detected and plays sound. Hurrah!
However, I know that the original slot is not bad because the card works in Windows. Therefore, there seems to be a problem with Ubuntu being able to find the card on that slot. Although my personal issue has been resolved, I am leaving the bug open because the root cause has not been fixed. I am willing to help diagnose why Ubuntu can't find the card on the original slot. There may be other people who need both slots. For what it's worth, the slot that does not work is at the bottom of the motherboard.
