Help plz!!

Please understand everyone here provides their time and help on a volunteer basis. I try to help when I can and have the spare time so can't promise fast turn around with replies. I try to get back within 24 hours. Sometimes faster, sometimes not. If you need immediate assistance/turn-around with your problem, take it to a computer repair shop. Now, back to topic

Here's what I see
You have High Def (HD) audio on both your lenovo motherboard and on your Nvidia graphics controller. fyi.. Windows connects to HD audio like this
Windows <===> HD Audio (HDA) Controller <===> HD Audio Devices​
The HDA controller, appears in DevMgr under System Devices. You'll see two: one for the HDA controller on the mobo the other for the HDA controller on the nvidia card.

I'm not certain, but it appears the HDA controller on the mobo isn't detecting the Conexant device at the moment. The Conexant driver install may be failing because it's not detecting the Conexant HD device. Are you getting an install error message something like "Hardware or Device not found"?

Re-installing the HDA controller driver causes it to search for devices again. Maybe it will cause it to re-detect missing devices. Let's do it for both controllers
> Under System Devices, right click each HD Audio Controller. Select Uninstall
> Now reboot your computer. The driver for both controllers will reinstall

Do you now see any DevMgr entries with a yellow icon appear? That would be the Conexant device (missing the driver). Try the driver install again

Well first of all I don't get any "error message" while trying installing the driver,it just says it faild to install...

I deleted the two HD Audio Controller under System Devices and reboot and now I have 5 unknown devices with a yellow icon under "other devices" in DevMgr ,and I can't update them nor installing the Conexant drive...

And I dont think it reinstall anything

I know the instructions are simple but are you certain no items are listed? Anything is possible with computers, but given your situation, that seems impossible (or at least very bizarre) to me.

Can you provide a snapshot of Device Manager with all those yellow icons showing. That will help me some if nothing appears under Problem Devices

I have your Device Manager report.

Kewl. DevMgr display device hierarchy would be right-to-left for Hebrew.

Try Misor's suggestions. If that doesn't work could you translate the items with the yellow icons PLUS their parent entry that has the question mark.
 
If you still have a problem after Misor's suggestions, It might help to switch to English temporaritly. Under CtlPnl->Region and Language set Format to English. On Admin Tab, set Language for Non-Unicode to English

See if any Problem devices show up now? Does Device Manager appear in English?

Well ok,

First file is the end result after trying installing the conexant audio driver as misor suggested(which I tryied before anyway)

And the translation :
items with the yellow icons-"unkown device"
parent entry -"other devices"

That makes sense, and normally Problem Devices would show an entry for each of those Other devices (that's why I'm so surprised nothing show up... unless, perhaps it's because of the different language? IDK

I gotta step away for about an hour or so.. but will be back to take a look

/* EDIT */
Try switching Region and Language settings to English for now. Might make it easier
 
Have you tried setting the Format and Region to English? (per above post) Might help in further debugging

I think maybe part of your problem is the High Def Audio Controller driver on your Win 7 machine is corrupt. (It comes packaged inside Win 7) Check to see if each of these files exist
C:\Windows\inf\hdaudbus.inf​
C:\Windows\inf\hdaudbus.PNF​
C:\Windows\System32\drivers\hdaudbus.sys​

Still hebrew even after changing Format and Region to English
And all the files do exist
 
That Windows driver is corrupt. Windows Hi Def Audio Controller should reinstall itself when windows detects the 2 HDA controllers on your machine (one on the graphics card, the other on the mobo)

I can see in your DevMgr report both these devices are detected but no driver installed (they are two of the "Other Devices". Other Devcies are hardware detected without a driver)

Like I said earlier, until the controller is working the devices won't work. (Since the controller doesn't work, the Connexant device installation fails)

I can look further (probably with no reply till tomorrow). This driver comes packaged as part of Windows. The Conexant driver won't install till the controller's working

You might just want to do a Win 7 reinstall. Or if you have a Win 7 disk, try doing a repair. In any event, will try to follow up with ya tomorrow.

Someone else may have other opinions. But, for me, this is what I'm seeing in your data
