Re: W520 bad microphone??? Usable!

[ Edited ]

How do you uninstall the drivers and get the (working) windows ones?  I tried this:


  1. Hit start button (bottom left of screen usually)
  2. Type "device" into the search box
  3. Select "device manager" from the list
  4. click on "Sound, video and game controllers"
  5. right click on "Conexant 20672 SmartAdio HD" and hit uninstall
  6. select "Delete the driver SW for this device" to stop it being installed again.



But when it comes up, it still has the rubbish conexant drivers - I cant see how to get it to pick up windows drivers.


Any ideas?

Try installing the Realtek High Defintion Audio Driver for Windows 7 package on the ThinkPad W530 Drivers and Software page.

Btw, this should solve problems 5 and 6 on your signature.

I have the Edge E430 model and the sound is alright and the microphone works out of the box. Do you know if the guides here are still relevant and can provide some audio improvements?


FYI, the new Edge models come with the Conexant HD Audio driver and Dolby Home Theater v2, which I suppose is not so different from v4:

thanks "Disable audio enhancements"  seems to have fixed it for me as well.
