Sigma Tel update kills sound

I have home premium, upgraded from home basic.
Yesterday MS notified 4 updates available, 3 were Microsoft and 1 was
SigmaTel high definition audio codec. I installed the updates.
But the speaker icon when moused over now said "no audio output device
installed", and there was no sound. (Before, said high definition audio
device.)
I restored back to just before the update, and sound was back to normal.
Anyone have an explanation or solution for this?

From past experience, unless you have a problem with the hardware, don't
update the drivers. Especially drivers from MS. Go to the manufacturer's Web
site for the drivers instead.
