Hi rincewind_et: We will assist you with this scenario.
We recommend to install the drivers provided by the manufacturer of the laptop, those drivers were customized by them to work with your specific platform.
I looked for the drivers for your system and the model you gave us is not showing on HP's web site:
Please follow the steps below to try to fix this problem:
-Open Device Manager >Select "other devices", click on "Realtek HD audio" >Update driver
-Click "Browse my computer for driver software" -Click "Let me pick from a list of available drivers on my computer"
-Click "Sound, video & Game devices" and Then proceed as normal
-Select "Realtek" from manufacturer > Install Driver Version "22.214.171.12450", Not the updated "126.96.36.19931"
If the problem persists after that then we can try the following steps:
Perform a system restore to a point when the audio was working, and then update the graphics driver to version 188.8.131.5226 or newer.
Steps to perform a System Restore on Windows® 10:
-In the Search option located in the start menu type in Restore
-Create a Restore Point' should show up as best match, click on it.
-Click on 'System Restore'.
-Click on 'Next' after the initial Wizard screen.
-Select either 'Recommended' restore point or -Choose a different restore point' if you have manually made previous backups.
-Select a restore point from the list of available options.
-Click on 'Next' to finish.
If the problem gets fixed after trying the steps above, the please install the latest graphics driver available for your system to avoid the problems described on the following link:
