@PekinBill

Thank you for replying with the results. 

The final option is to reinstall Windows. This might help. Because so far we have tried to reinstall the drivers, check various settings and still there is no option for the Stereo Mix.

To perform a system recovery you may refer to the steps mentioned under "Recovery when Windows 10 does not start correctly" from this link: http://hp.care/2jvXEdP

I really appreciate your patience and wish you good luck! Keep me posted.

I've seen it suggested elsewhere in this forum that this is a HP hardware issue and that HP have failed to address it.  I have the same issue and nothing seems to help.

Is it likely that HP will hold up their hands and admit that this is a serious design failure with their machines and then do some positive to help the people who've spent money on an HP machine only to find that it cannot be used for the application that's importeant to them.

I'm at my wits end here...

Try this: https://www.youtube.com/watch?v=moCA6jQ5TP8

it worked for my HP Spectre x360. I couldn't add this answer here: https://h30434.www3.hp.com/t5/Notebook-Audio/Stereo-Mix-Windows-10-and-the-Spectre-x360/td-p/5445514

I am delighted to report that this method worked for me after trying everything else I could find and failing.

Thank you very much for this fix.

It may sound hacky, but you can try installing drivers that are meant for another computer.  The point of this is that the install package would install Stereo Mix as it would on a computer that is supposedly compatible with it.  Since Stereo Mix is software-based and HP doesn't restrict driver 'cross-contamination', installing Stereo Mix on an ultrabook like the Envy 13t is possible!  If you're not sure where to start, you can try installing the audio codec for the Pavilion bc400:

And whatever you do, always reset when it promts you to!
