I just checked my Chrome extensions and found nothing for Google Play Music or YouTube in there. I did find a post on TenForums that explains how to set Chrome to enable or disable it's media hardware key handling settings. https://www.tenforums.com/tutorials/134484-enable-disable-chrome-exe-volume-control-media-key-handling.html Simple fix if it IS Chrome that's hijacking your media keys.

On my K70 in Windows 7 Pro, I would have the onscreen display of volume level (let's say it was manually set at 68% using the taskbar icon) when I rolled the dial or hit the mute, but nothing was actually affected on the PC. Starting the service fixed my problem as soon as I started the service. I think I may have disabled it trying to diagnose the volume control on an old Microsoft keyboard. Thanks!
