A concise, model‑agnostic troubleshooting workflow follows. Earlier replies already pointed to the missing OS-level audio bus component and to reinstalling the audio driver (, ), and suggested a clean reinstall. The steps below fill gaps those posts left out and focus on actions that reliably fix detection/installation problems without repeating links already posted.

  1. Verify exact Windows edition and whether it is 32‑ or 64‑bit (this determines which driver package to use).
  2. Install the laptop chipset drivers first (vendor/Intel/AMD). Chipset support is often required so the audio driver can attach to the system bus.
  3. For older Windows (eg. XP-era), install the OS prerequisite audio support package before the HD audio driver; for newer Windows the OS usually supplies that component. Use the laptop maker or Microsoft sources—avoid random driver mirror sites.
  4. In Device Manager remove any audio devices (right‑click → Uninstall). If shown, check “Delete driver software for this device.” Reboot, let Windows detect hardware, then install the manufacturer’s audio package matching the OS.
  5. Confirm the audio device is enabled in Playback devices and set as the default; check system volume and any physical mute switches.
  6. Ensure the services “Windows Audio” and “Windows Audio Endpoint Builder” are running (services.msc).
  7. If still silent, test with headphones or a USB sound adapter and, if possible, boot a live Linux USB to rule out hardware failure.

Cautions: always use the laptop manufacturer, Microsoft Update Catalog, or the official audio chipset vendor for downloads; match OS version and architecture. This workflow expands on and ’s driver prerequisites and complements ’s reinstall advice, and it resolves the majority of installer/precondition and detection issues without relying on third‑party installers.

You'll need to install Microsoft Bus Driver first before HD Audio driver could be installed successfully.

You'll probably don't understand Japanese so just scroll down till you found a link looks like this but it's for WinXP. there's a Vista driver as well but I don't know the OS you're running right now...

0610VXP1.EXE( 96,256,474 Bytes)

Download it and run it. If it's installer language is Japanese as well, reply here back so I can guide you step-by-step for it... (Only do this if you use WinXP)

Alternatively, you can use my second link or search google for Microsoft Bus Driver.

then there might be some problem in your driver still:) un install the driver, reinstall your hardware then try again to install the driver
