I'm using a Core 2 Duo 2.16 Ghz macbook pro and I recently upgraded my XP
installation to Vista Business. Seemed like I have similar problems as most
people, but the suggested solutions dont work. The biggest problem is that
i've got no sound. On first launch Vista device manager told me my audio
driver was signmatel with no problems (ie the device is working properly) yet
my system tray icon said sound device not recognized. I spent like 4 hrs
rummaging around the internet for a solution, and finally found a post on
InsanelyMac.com with a link to a set of drivers from
. After installing
those my system tray icon shows audio device recognition, but device manager
shows problems. Initially there was a single entry in device manager under
'Sound, video and game controllers', but now there are three with all of them
labelled SigmaTelHigh Definition Audio CODEC; the first one shows no
problems, but the rest show the yellow !. I tried right clicking and Updating
driver, but windows tells me that the drivers are already installed.
Bottomline, even though system tray icon provides volume control and shows
driver recognition, i have no sound on my Macbook pro. If someone can help me
figure out a solution, it'd be much appreciated.
Also my iSight and bluetooth doesnt work, if by chance you have any idea as
to how to get them to work, please post.
