I have the same problem on my Sony VGN-SZ4XWN. The only way I could get
round the problem was in Device Manager in System in Control Panel. I found
the uadio device and updated the driver the generic Micrsoft driver and got
sound back again. I then received an update to the Sigma Tel High
Definition Audio CODEC which was supposed to specifically address the
problem of loss of sound on upgrading to Vista Ultimate, but alas still no
sound so back to the generic driver.
