Conexant Sound driver issue with Windows 10 update and flash

[HanselNewAckers]

I had a problem with the combination of Windows 10, Adobe flash and all the browsers (Edge, Firefox, Chrome) Flash would not work. So I thought that this would be solved with the new update of Windows 10 version 1709 . Unfortunately my problem migrated from Flash only not working towards the sound stopping to work. I use the troubleshoot sound option from Windows and after restart the sound works for a short time. Than it stops working.

Hi! @HanselNewAck, Welcome to HP forums.

I understand you have audio and flash issues with your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your laptop?

Please provide the product number of your PC to assist you better.

As you mentioned after updating the windows to 1709 you have audio and flash issues with your PC.

Please try the steps recommended below.

Go to Control Panel -> Devices Manager -> Audio, Video and Games Controllers

And find there Conexant audio card. Click on it with the right button of your mouse and choose ' Properties '.
Select ' Driver ' tab and select Roll Back Driver check if the issue persists.

Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Conexant High-Definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
Right-click and select Update Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of device drivers on my computer.
You should see a window that says Select the device driver you want to install for this hardware. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Conexant High-Definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

Is the loudness equalization off? If not, please:
Right, click the speaker icon
select 'Playback Devices'. 
Highlight the default device
Click Properties
Click Enhancements tab
Next to 'Loudness Equalization' take out the check mark in the box.
Click Apply
Click OK

If the issue still persists uninstall the audio driver from device manager and install the drivers using HP recovery manager.

Refer this article to know how to restore drivers using HP recovery manager.

Try the steps recommended below to solve flash issues with your PC.

Go to Control Panel > Internet Options. Select 'Advanced' tab at the top.

Tick 'Use software rendering instead of GPU rendering*', then click OK.

Re-open the Browser and check if it helps.
