Hi: If you installed W7 32 bit you should be fine manually installing the Vista driver on your notebook's support and driver page. If you installed W7 64 bit, you are out of luck and if you want the audio to work you need to install W7 32 bit. Download and run this driver.if it installs automatically, great.
Go to the device manager and click on the multimedia audio controller needing drivers. Click on the driver tab.
According to the device (4370) and vendor (1002) code, it should be the ATI IXP AC'97 Audio Controller chip, and the driver corresponding should be the realtek one. It installed well, but don't work since a code 10 is displayed.
Click on Update Driver. Select the Browse my computer for driver software method and at the bottom of the window select the Let me pick from a list of device drivers on my computer. Select Have Disk and browse to: C: SWSetup sp34567 CPL309Ba, and select the Conexant AC-Link Audio device from the list and see if the driver installs that way.
