no audio output device on vista T43

[zaku]

i used the system update software from lenovo to install all the necessary software after a clean install of vista. but i can't get to have audio output (no sound). and i can't seem to find the audio driver for vista for T43 on lenovo website...

First you might try Windows Update to see if it finds the audio driver.

If not, try downloading the XP driver, then double-click on the download to extract it's contents. In Device Manager, choose Update driver and point to the directory the files were extracted to: C:\DRIVERS\WIN\AUDIO\

oh thanks i got the sound now.. i did the windows update and it installed the audio driver

but now after the update, it came out another problem, the on screen display is no longer there even though the FN keys are still working.
also i cannot logon anymore to the domain it always displays "the trust relationship between this workstation and the primary domain failed" whenever i log on.. it was working before the update though..
