Unfortunately I'm experiencing the same problem but with 17.04. The only difference to the previous reports that volume adjustment is happening in almost every second and the notification popup is visible constantly (it is flickering when the volume adjustment happens). So it is quite annoying. When I remove my headphones from the front audio jack, the autonomous volume adjusting stops. Interestingly i have never had similar problems with any of the previous versions of Ubuntu (starting from 12.04).
