Since the first day out of the box, the Envy x360 audio frequently stops working and requires reboot just as often in order for sound to work again. During the problem, there is no sound--neither from either speakers nor headphones. This problem only happens after laptop is closed, goes into sleep &/or hibernation, and is later switched back on; it never happens in the middle of being on & running.
Many of the relevant troubleshooting steps on these forums have already been tried: checked mute & volume settings, uninstalled & reinstalled updated Windows and HP audio drivers, tested Windows Troubleshooter, checked listed Realtek Audio "output device" setting, checked in Device Manager that Sound, Video, & Game Controllers as well as Speaker / Headphones output are enabled, etc.
Lastly, during all sound tests with Windows, audio levels graphics respond as if sound is playing even though it is not.
