Sound on my computer just went way up with no longer control.

As I was listening to a lecture at a volume setting of 26 the volume panel appeared and went to 100. I tried to lower the volume but it will not go down. I have re-installed the HP audio driver and re-booted the computer and it work well for a while and the just goes to full volume again. I closed off all applications and any computer notifications still come in at full volume.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help,  I have a few troubleshooting steps we could try to fix the issue:  

Let's uninstall the audio driver from device manager, 

1. In Windows, search for and open Device Manager.
2. Double-click Sound, video and game controllers.
3. Right-click the sound device and select Uninstall.
4. Restart the computer to reinstall the driver.
5. Test for sound. If the audio problem persists after reinstalling the driver, continue to the next step.
