No sound after clean Win 7 install

I did a clean install of Win 7 64bit on a Lenovo ThinkPad and cannot get the sound working. Realtek HD audio drivers are up to date. The system thinks the sound is working but nothing from speakers.

I installed the Hotkey features for the lenovo and have manually adjusted the sound from both the tray and the Hotkey. Volume is 100%.

I ran this computer for 2 years using Linux Mint and the sound worked out of the box, even the hotkeys. Never an issue until I installed Windows two days ago.

I have searched high and low for a solution to no avail. Note, this laptop came pre-installed with Windows 7 and no issue with the sound then. I know the hardware is good. This issue is very frustrating.

Anyone have any suggestions??

  1. You did install sound driver package from Lenovo I assume, not from Realtek's website?

    Yes, I installed all driver packages from the Lenovo site. In fact, I've tried everything I know. I've never had an issue like this before....never had to ask for advice on a website. I'm completely stumped.

    I can't think of anything else to suggest - except, did you install the "chipset" driver too?

    The chipset driver should be installed first, then the sound driver.

    Thanks for your replies, Phillip.

    Installed the chipset driver also. Not sure of the sequence though, nor how to undo those two driver installs and re-install in correct order.
  5. No need to uninstall the sound driver if you think you may have installed it before the chipset driver. Just install the chipset driver again, followed by the sound driver again.

    As a rule, in future (and this applies to all motherboards) install the chipset driver before any of the other drivers.
