HP Envy 15 x360 PC - No Sound

[EC-Joe]

I have two of these computers and am experiencing the exact same issue with both, the sound does not work.  When I play a video, I can see the sound bars next to the play back device. There are many reports of this issue and I have tried every troubleshooting tip that I can find to fix it.  My daughter needs to have the sound working to complete her school work and take her AP exams.

Welcome to HP Community

I have gone through your Post and would like to help
 

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

If the issue persists run an Audio Test from F2 Diagnostic and let me know if that helps

- Hold the power button for at least five seconds to turn off the Notebook.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Audio

Keep me posted how it goes

Thank you and have a wonderful day 😊
