Splendid effort and fabulous description of the issue before posting. Kudos to you on that score. You are a valued HP customer and it is paramount to assist you here. I take it as a privilege to share this platform with you.
As you have mentioned in your post that you have tried the steps suggested in the previous post and unfortunately nothing has helped to resolve this issue. Don't worry as I have a few other steps which should help you resolve it.
Let's uninstall the audio drivers from device manager:
Right-Click on start button> click device manager> expand sound video and game controllers>then select the sound drivers and right-click on it and uninstall the audio drivers.
Then check the box delete the software for this device.
Now restart the computer and then update the Bios, Chipset and Audio drivers on your PC from our HP support website, using this link.
Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.
Refer this link to know how to use HP support assistant.
If you are not sure which driver should be used for each platform, please run a “Check for Updates” from Windows Update to get the latest audio driver from Windows Update.
Please let me know if this resolves the issue, or if you require further assistance!
Eagerly waiting for your response!
