A Conexant audio device could not be found. The application will now exit.

I have a brand new notebook (purchased 11/2017), and today (day three), suddenly, the audio stopped working.  The speaker icon in the notification area shows a red X next to it.

When I restart the computer, I get this error message:

A Conexant audio device could not be found. The application will now exit.

I have run the audio troubleshooter, but it says "Troubleshooting couldn't identify the problem."

In the control panel for sound, under the playback tab, it says "No audio devices installed"

Later Update: I contacted HP Support via a chat session.  They helped me reinstall an aduio driver.  When that didn't immediately solve the problem, they then had me run an audio hardware test (power down loadtop, power back up tapping F2 function key to initiate hardware testing options).  The diagnostics utility ran the audio test and test results said it passed.  When computer booted back to WIndows, problem was resolved -- my audio was back.

Don't know why this happened to begin with, or if it may happen again.  Hope not.

I called HP about this and they did exactly this "fix". About a week later, the issue came back!
