New Dell P2717H Monitor and new AC511 Dell Soundbar connected to older Dell XPS 8700 Windows 7 computer.
Sounds are fine, but Direct Control Volume Level dial on right side of soundbar DOESN'T change volume.
2 of my clients that I was with today have Dell systems with soundbars that were ordered at the same time as their system (1 is Windows 7, 1 is Windows 10) where dial works correctly. I am on frequent conference calls and must have ability to increase/decrease speaker volume instantly (without going to icon on system tray).
Dell sent replacement soundbar .. same issue! (boo) Latest driver appears to be installed.
Dell seems puzzled!! ANY/all ideas welcome.
