One week ago I bought a brand new Lenovo G 580 laptop and everything worked okay until I updated the OS to win 8 PRO 64bit and the audio interface stoped working.
I have sound - with the windows mixer thing, but when I downloaded the win8 driver for dolby advanced audio v2 from lenovo website the sound doesn't pass through the software anymore.
Do you have any clue why it's like this? I really hope there is a fix for this because without the dolby processing now the sound is very low and dull.
Thanks in advance!
P.S. : Sorry for my english, if you find mistakes - I'm from Romania and I am really in a hurry right now.
Solved! Go to Solution.

Thanks for posting and welcome to the Lenovo Community,
I’d like to advise you to uninstall the Sound drivers installed on your system from Device manager under Sound,video and game controller,
And also please uninstall Conexant HD Audio and Dolby Advanced Audio v2 from control panel and then programs and uninstall a program,
And then please install the below links:
Hope the information helps. Let us know.

I tried that, actually I tried all the solutions and the result is the same. I have sound, the dolby advanced audio control panel is in the taskbar and I can open it but the sound does not pass through dolby sound interface.
L.E. : And yes , the Dolby Advanced Audio is ON, not OFF. But with no luck.

Well yes you can install it on win 8 but it doesn't work. I don't know if the problem is general but I really hope there is a fix for this, I need this thing to work, Lenovo.

Sorry for the double post, but STILL THERE IS NO SOLUTION TO THIS?
I searched the holly wide web and found that there is a newer version of the conexant smart hd audio driver -
v 184.108.40.206 which Lenovo doesn't have. Now why is that? It's Dolby's fault or Lenovo's? Why is the feedback so bad? I mean, all I have read here from the oficials @ Lenovo are simple and logic solutions that I tried myself in the 1st place, there is nothing tech savvy in that answers.
And yes, I know w8 is fairly new but why the heck stil needs tweaking from the manufacturers, in this case for a audio interface?That's something that was supposed to work from day one - the drivers! (It's been so long since Windows 8 was launched, what the hell?)
L.E. : I FIXED IT! I was not looking for this but i did it! In device manager was a unknown device that requested driver. I uninstalled it. After that, 3 hours later I installed lenovo energy management utility which asked for a restart. After that I realized that Dolby Advanced Audio V2 IS WORKING!
L.E. 2 : Update :If what I wrote above does not apply in other cases, I came across another aspect -> In Speakers Advanced Settings I had the sample rate and bith dept set @ 24 Bit, 192000 Hz. If you choose that setting or 24 Bit, 96000 Hz the Advanced Audio V2 will not work anymore. The highest supported by the Dolby interface to work is 24 Bit, 46000 Hz - the one I use now.
