No audio device installed - ? Win Update related

Trying to fix a friend's Dell Inspiron 1501 laptop, Win Vista SP2, which has lost sound round about a week ago. Possibly related is a bootup problem from about the same time where it sometimes but not always sticks at the Welcome screen - Ctrl Alt Del twice forces it to start.

There are recent posts on this forum for each problem, just wonder if they are related.

Extensive search of forums seems to point to a
recent Win Update as the culprit for both, although the sound problem has references going back a couple of years. No joy so far. Uninstalled the recommended update 905866 from 17/1/10 which someone else suspected by no joy either.

Anyone else got these problems, especially the sound? My Gateway Win Vista and Acer Win 7 starter are both ok.
