Hi, sorry if I've started this thread in the wrong place - I've never needed to request help with a computer problem before.
I have a Lenovo G510 running windows 8.1 64 bit, bought about 6 weeks ago. Installed windows updates earlier today, including an optional one for the conexant audio device, and now there is no sound. There is an exclamation mark next to the device in device manager and an error code for the driver that states 'Reinstall the drivers for this device. (Code 18). I have tried uninstalling and reinstalling many many times, including downloading the driver from the Lenovo website and using the driver from the D drive, always with the same error:
Windows encountered a problem installing the driver software for your device.
Windows found driver software for your device but encountered an error while attempting to install it.
Conexant SmartAudio HD
Reinstall the drivers for this device. (Code 18)
I've also tried doing a system restore to before the update but this also failed with the message 'access denied'. Update history states the audio device update was successful.
The events tab in device manager shows a list stating 'device installed' over and over. The information for the most recent event is as follows:
Driver Management concluded the process to install driver g13plmwa.inf_amd64_007bf12cd0f50a21\g13plmwa.inf for Device Instance ID HDAUDIO\FUNC_01&VEN_14F1&DEV_5115&SUBSYS_17AAC041&REV_1001\4&2426718C&0&0001 with the following status: 0x0.
I don't really know how to read all the info in the details tab but the capabilities property has a value of 00000000 which doesn't sound promising to me!
Status property reads:
01802400
DN_HAS_PROBLEM
DN_DISABLEABLE
DN_NT_ENUMERATOR
DN_NT_DRIVER
Sorry for the very long post, really hope someone out there can help, have spent most of today trying to sort this. I was already incredibly frustrated with windows 8, now I'd quite happily murder anyone involved in the development of it with my bare hands.

Ok, I realize you've done a bunch of installation attempts but I'd try this just to be sure.
Uninstall the driver package in Programs and features, again.
Open device manager and navigate to Sound, Video and Game controllers and right click any listed audio devices and select "uninstall" and check the box that says "uninstall device drivers".
Reboot.
Install the drivers found here (You might want to download these first):

Hi, thanks for the suggestion darkbreeze. I would have already tried to uninstall the driver package from the programs list if I could see anything there it could possibly be. I guess this is an indication of a problem in itself. I have been uninstalling and reinstalling from device manager. I think ensuring it's completely uninstalled would certainly be a start to trying to fix the problem but I don't know how to do this and don't want to start deleting files unless I'm sure I know what I'm doing.
Also, since I posted the problem I discovered that the driver update in question is still listed in windows update (now as 'important'). So I've downloaded and installed and restarted several times but still with the same error message (though sometimes it changes to Code 1, "this device is not configured correctly"), and the update is still listed in windows update. Update history states the audio device update was successful - every time I've downloaded and installed it - however it is not listed in 'installed updates'.
I've had to disable the audio device because it was massively slowing down startup by the way, windows was trying and failing to install the driver every time I turned the damn thing on.
Any other suggestions gratefully received...

Go into windows updates and right click on that update and select "hide update" Then uninstall all related drivers through device manager as best you can. Then reboot and install the drivers from the link I gave you before. The Microsoft generic driver that shows up in windows update causes everybody problems and most likely does not work with the hardware in your laptop. The above driver should be the 8.1 compatible one.
Even on the Microsoft website they recommend installing the updated Lenovo driver rather than their own, as seen here:

Thanks again Darkbreeze but uninstalling the driver, rebooting and then installing the most recent one downloaded from the Lenovo website was one of the first things I tried. I've just tried it again just for the hell of it with the same result:
Windows encountered a problem installing the driver software for your device.
Windows found driver software for your device but encountered an error while attempting to install it.
Conexant SmartAudio HD
Reinstall the drivers for this device. (Code 18)
Incidentally, the driver update in question isn't a generic MS one, it says it's Conexant SmartAudio HD. It appeared to be a more recent version than the one I had which is why I decided to download it.

Yup, someone else suggested that too, didn't flag up anything relevant though. Any issues it did flag up have been fixed using DISM restorehealth.
So, I think all the necessary driver files are there intact but something is preventing them from installing properly. I'm wondering if it could be anything to do with the firewall (ZoneAlarm) or the antivirus (avast) I'm running, or a conexant/realtek conflict - I've read about that in some forums. I seem to have a realtek card reader installed but the 'audio device on high definition audio bus' is conexant. I've already tried uninstalling the realtek card reader by the way.
Any other suggestions anyone? Any sound card gurus out there??
