No Audio with Macbook Pro

I get no audio within windows and when I bring up an Volume control it says "There are no active Mixer Devices available."

I have tried updating the unknown PCI device automatically and by pointing to the drivers on the leopard CD. It couldnt find them. I also tried pointing to the realteck drivers off thier site but it wouldn't take it as realted to the hardware.

Installed thoes drivers off the realtech site.

I seem to be having a simular problem as many but thier solutions were not successfull.

makbook pro, Mac OS X (10.5.1)

If my memory serves me right the Realtek drivers are compressed on the Leopard DVD so point the driver installer to it won't help. Try running RealTekSetup.exe directly from the Leopard DVD under Drivers.

Tried all three!

HERE is something interesting. while installing all the drivers once with the exe of thr CD. 2.0 drivers. Once it gets to sigmaTel it says another instance of this program is already running. Please wait for the other instance to finish and try again.

No other instance of it is running! and the instillation finishes! whats up?

I think I've found a solution.

After failed manual installs of both RealTek and SigmaTel drivers supplied on Leopard disk that came with MBP, I noticed a 'PCI Device' with ! mark under System Devices in the Device Manager.

Right click that and choose reinstall/update driver or whatever whatever and let it reconcile this device to the RealTek driver and all should work (you should hear sound without having to reboot).

Hope that helps someone.

Found the device manager, but when I try to reinstall or update it requires me to find the location of the driver installer. Is this installer within the MacOs X 10.5 System disc?

There is a RealTek installer that I had already ran that and I'm assuming the driver was installed then, thus I didn't need to put a disk in.

Did you find the 'PCI Device' with the yellow exclaimation ⚠ ?

So again in summary I manually ran the Realtek installer (HD audio device) from the Leopard disk and after rebooting I triggered a driver reinstall/update by right clicking the yellow ! marked PCI Device and that seemed to do it.

Yes, I found the PCI Device with the exclamation mark, but when I click reinstall a new window pops up, it is a program, or sort of, that searchs for the wizard. It is set to find it automatically, but turns out it doesn`t. If I click a manual selection, I select to search in CD and thw whole hard drive, and still doesn`t find it. Any idea were is it exactly?
