OK I posted a similar question in macrumors, usually they help me out of jams but not this time. So I downloaded Windows 7 on bootcamp something or other I think 3.9. I have 10.5 on a macbook. So a few drivers didn't install properly. I think. So I don't have sound. I want to download the windows version (32 bit) of the driver for my sound device. Its called "High Def Audio Device" So you can see where I have trouble finding a driver. Can someone point me in the right direction?

For — the correct source for the Windows audio driver on a Boot Camp Mac is the Apple Windows support software (the Boot Camp drivers) for the exact Mac model and Windows bitness, not a generic “High Def Audio Device” download from a random site. ’s suggestion points at a third‑party driver archive; those sites are risky and often supply the wrong package or bundled extras, so prefer Apple or the component vendor. (support.apple.com)

Practical options (pick whichever fits the setup):

  • If the Mac still has its Mac OS X install disc (Leopard/10.5), start Windows, insert that disc and run the BootCamp\setup.exe (or choose Repair) to install Apple’s audio drivers. The Boot Camp manual documents this exact flow and what to expect during installation. (manualzilla.com)
  • If there’s no disc, use Boot Camp Assistant on the Mac to “Download Windows Support Software” to a FAT-formatted USB drive, boot Windows, then run setup.exe from that USB. That will install the Apple-supplied audio driver (and other device drivers) appropriate for the machine. (support.apple.com)

Troubleshooting tips if sound still fails:

  • In Windows Device Manager expand “Sound, video and game controllers” and note the vendor name (Realtek, IDT, Cirrus, etc.). If Windows shows only a generic “High Definition Audio Device,” try uninstalling the device (check “Delete driver software”), reboot, then run the Boot Camp setup.exe (or use Update Driver and point to the BootCamp\Drivers folder). Microsoft’s troubleshooting guidance covers using the generic driver, uninstall/reinstall, and getting drivers from the device/vendor site if needed. (support.microsoft.com)

If Boot Camp’s package doesn’t fix it, identify the codec listed in Device Manager and download that manufacturer’s Windows driver (from the vendor site). Avoid automatic “driver updater” utilities; they often make things worse.
