Re: audio device on high definition audio bus

i am having the same isssue and i think lenovo support in UAE is so poor.. if a lenovo employee can support us, it will be great full regarding my audio driver issue. Because my mic is not yet working. and more over if you find the keepboard layout you will wonder where you will find @ symbol. probably lenovo may make the laptop in C Grade industry of china..... where you can make things cheaper like anything.

hey dude i solved that issue same as you if your using xp for audio issue try to load driver manually in C:\DRIVERS\WIN\AUDIOC\WDM, for video issue in HDMI audio i think you need to install again the video driver due of HDMI and if install the driver point or locate the video driver folder at C:\DRIVERS\WIN764\VIDEO\HDMI it is because the audio and video has same HDMI system files needed, sorry my bad english but im trying to help.

 

thanks

Re: audio device on high definition audio bus

Hi Guys,

 

I hope your problem would be resolved but, anyway, if not, i have a solution for you.

 

I got the solution from Chinese website. It is stated that you have to download Video driver into your SL400. Then, execute it. You will see it is extracted into C:\DRIVERS\WIN\VIDEO

 

Well, now you just do not do anything. Go back to your Computer manager where an unknown device is shown. Click on it and select update driver. Finally, point the driver browsing to C:\DRIVERS\WIN\VIDEO\HDMI

 

Then, enjoy using your SL400..

 

Cheers

 

Note: I could not read chinese. I just guessed and luckily it worked.
