Enabling Lenovo N100 SoundMax audio in Windows 7

 
I recently installed Windows 7 in my Lenovo 3000 N100 laptop. The installation went well and everything seemed perfect until I discovered that there was no audio. I checked the Device Manager and found no errors related to audio and others. My techie instinct tells me I needed to manually install the driver. Since no driver was available for Windows 7 from the Lenovo support website, I took the risk of dowloading the Windows Vista driver instead. After the download, I immediately installed the said driver but to no avail. Instead, Windows 7 loads its own high definition audio driver even when I uninstalled it and rebooted the machine. I searched the Internet for hours hoping I’d find a solution to the problem but become frustrated even more. Out of desperation, I did the following procedure to eventually solve the problem.
 
   1. Using Windows Explorer, open the C:\windows\system32\drivers folder.
   2. Select and right-click HdAudio.sys then select Properties from context menu.
   3. In the Properties applet, click the Security tab.
   4. In the Security tab, click Advanced then click the Owner tab thereafter.
   5. In the Owner tab, you should see your username listed, click Edit.
   6. You should see your username listed again. Select it and click OK.
   7. Click OK when a message box appears.
   8. Click OK again and click Edit.
   9. Click Add and click Advanced then click Find Now.
 10. Select your username and click OK and another OK.
       Notice that your username is selected.
 11. Tick the Full control checkbox and click OK.
 12. Click Yes when prompted and click OK.
 13. Delete HdAudio.sys and do the same for the other copies located in the following folders:
      * C:\Windows\LastGood\system32\drivers
      * C:\Windows\System32\DriverStore\FileRepository\hdaudio.inf_x86_neutral_9781e9d72e255b2e
      * C:\Windows\winsxs\x86_hdaudio.inf_31bf3856ad364e35_6.1.7600.16385_none_15368bf2c8c39eac
 14. Download the driver from Lenovo support by clicking HERE.
 15. When the download is completed, extract the SoundMax Vista driver by double-clicking it.
      By default, it will be extracted on C:\Drivers\WIN\Audio.
 16. Open the C:\Drivers\WIN\Audio\i386\Vista folder.
 17. Copy ADIHdAud.inf and ADIHdAud.sys to the following:
      * ADIHdAud.inf to C:\Windows\inf
      * ADIHdAud.sys to C:\Windows\System32\drivers\
      just click Continue when you encounter an access denied dialog box.
 18. Launch the Device Manager and expand Sound, video and game controllers then uninstall High Definition Audio Device.
 19. Reboot your computer.
 20. After the reboot, launch the Device Manager and double-click Audio Device on High Definition Audio Bus under Other Devices.
 21. Click the Driver tab.
 22. In the Driver tab, click Update Driver and select Browse my computer for driver software then select Let me pick a list of device drivers on my computer.
 23. Scroll down then select Sound, video and game controllers and click Next.
 24. From the list of compatible drivers, select SoundMax Integrated Digital HD Audio and click Next.  
 25. Click Close and another close then reboot your computer.
 That’s it. Hopefully, this works for you.

    Nik Bim, Hi.To rid my computer of all copies of HdAudio.sys, I launched the Command Prompt and did this: 1. Type cd / then hit Enter. 2. Type dir hdaudio* /s then hit Enter.All copies of the file should be listed thereafter, if there are any left. You then can change directory to the location of the file and delete it or launch Windows Explorer to go to the file location and delete it.Once your computer is free of the HdAudio.sys file, proceed with Step 14 and you should be able to solve the sound problem.Hope this helps…

    I figured it out you guys everybody who does not have the lastgood file i figured it out. Computer genius right,<—— sorry it took me about two months to figure it out. we have to take another route. when you download the file listed here pay attention to where it downloads. C:/ect……. go there if you use firefox which everybody should you install it to your computer. find it on your computer then click the setup. there is a file on your computer that says setup.exe with the logo from the file that came from the lenovo website when you double click the setup.exe file you will see a soundmax installation menu just install it and bam my sound worked. i didnt even have to restart the computer. email me at jester4113@yahoo.com for more details my name is Joey.
