HP ENVY - 17-bw0503na Product Number 4BA03EA#ABUExample: Pavilion 6530
Microsoft Windows 10 (64-bit)

Laptop approx 2 years old during which time internal mic response via Skype, Zoom, Audacity audio and internal video has been good. In the recent past the quality has deteriorated resulting in crackling. I have gone through audio tests with HP so far to no avail and have had to resort to Microsoft LX3000 headset Microphone which is good.  Obviously due to close proximity of the latter, the output on the test bar is good whereas the output on webcam mic is low. Could it be anything to do with poor signal/noise ratio? I personally suspect Windows updates. Help! please

Please note that I am not getting crackly from my computer, I am getting it from my internal webcam.

Thank you for your help. I understand a hard reset involves having to re load all of my apps, a thing I am not prepared to do. The BIOS has already been done and the drivers are up to date. I am disappointed that on a relatively new and expensive HP computer that this problem can't be sorted. I use this computer, not for spending a lot of time trying to sort out its technical problems but to enjoy the facilities that it offers. I am still convinced that the problem is to do with Windows update.

On another matter. Is it possible to make the text Black on this web page instead of difficult to read Grey?  Some of us that use HP are doubtless elderly with poor eyesight.

You comments will be appreciated.

I understand your concerns.


In that case, I would suggets you perform the system restore.


System Restore is a software program available in all versions of Windows 10 and Windows 8. System Restore automatically creates restore points, a memory of the system files and settings on the computer at a particular point in time. You can also create a restore point yourself. Then, when you use System Restore to restore your computer to a point in time before an issue began, System Restore returns your computer to the files and settings from the restore point. Your personal files and documents are not affected.


You can also undo a System Restore if the restore does not resolve the issue or if the issue becomes worse.


Have a nice day!!
