Superb analysis and brilliant diagnosis of the issue before posting. 🙂 Kudos to you on that score. 🙂

For better clarity and to assist you better I would require more information regarding this:

For now please perform these steps:

• Windows Audio is a Windows service that manages audio for Windows-based programs. If at all this service is stopped due to any reason, audio devices will not function properly.
  To fix audio services, open the run command and launch services.msc.
• In the services window search for Windows Audio and right-click on it to select Start to start the audio service.
• And ensure the Startup Type is set to Automatic.
• Click Apply and OK.

Restart the computer and check if it works.

Same happened to me month ago and still no solution from HP! 

By a chance I discovered following work around - it is not "a solution" but more helpful than the tons of smiley's from a HP employee in this post.

After the Conexant audio driver was removed from my laptop due some "security issue" inumerous times I observed that it did not happen when connected to internet via wifi "Connection as Metered" in my second home where I use metered connection to avoid Windows updates which consume a lot of MB on my paid data. So I suspected that it was some Windows update algorithm which was removing the  driver. This I found confirmed on a HP page, where they recommend to install a new driver to resolve this issue - but Windows continues removing this driver too.

So the solution was blocking Windows updates. This can be done for Ethernet connection also: Connection as Metered www.howtogeek.com/226722/how-when-and-why-to-set-a-connection-as-metered-on-windows-10/

It is really annoying that HP even after a month has not addressed this issue and for sure lots of people are wasting time finding a solution. I am very disappointed to have bought  HP Probook 440 G4, it is too new to throw it away. It is not the only one audio issue I had to solve.

I my second home, where I use wifi connection, I have Bluetooth speakers which got disconnected unpredictably in a similar way as above. After reinstalling Audio and BT drivers all the time and no improvement I discovered, that it did not happen in my first place, where I use Ethernet connection. The solution was to disable WIFI. Later I red somewhere, that there really is a BT/WIFI issue on audio. Surprisingly this phenomenon disappeared after a month (some automatic update?) to make place the Conexant audio driver novel.

For what its worth, it seems that I lose the Conexant Audio after I have connected to Bluetooth Audio...

They need to escalate this entire issue. MANY of us are having the same problem with no solution provided from HP at this point. Every troubleshooting path is a waste of time. Some say they lose audio while using bluetooth. With 2 HP Envy X360 PC's in one month I have lost my audio no matter what I am doing--or not doing. Updating to latest driver is  a failed option. Updating the BIOS does not fix the issue. When I ran the hardware check prior to boot to test the speakers, per the HP support tech's instructions they passed just fine.

Rebooting or closing the lid and then re-opening it are the only fixes. 

I already returned one machine to the Microsoft Store, who simply decided it was a hardware issue and exchanged it. If this issue is not fixed I would imagine a substantial number of machines will be returned to HP.

I am in total agreement with you. Updating drivers, BIOS,... it's just a waste of time! Here I'm too, waiting [im]patiently a real solution from HP. I was expecting a reliable, solid laptop from such an experienced manufacturer!!  I would really  appreciate a statement from HP explaining what the problem is and they are going to do about it.

By the way, "Event viewer" shows an overwhelming number of errors of all types, some of them related with sound.

Please add me to the list of users suffering the same problem.  I have an HP Envy x360 15-aq100, purchased 4 weeks ago from HP.com.  I've attempted to use HP Recovery Manager to re-install the Conexant HD audio driver, which runs successfully to re-install the driver, but after a couple of hours, the audio device disappears again.
