Audio and video not synced

Watching movies and Internet video has the audio usually ~0.5 seconds behind the video.
I set Pavuconrol to +500ms on audio, so video and audio sync, but after a reboot, the video is 500ms ahead of the audio. Curiously, the pavucontrol settings show the adjusted =500ms audio.

The monitor is a Sony Bravia KD65X7000G.
